The Meaning of Life, the Universe, and Everything.
With iron farms changing in 1.14 to be about villagers at a meeting point, my question is, does that mean we can now only build iron farms in the new villages that have a 'meeting point' or does X amount of villagers around a town bell create one anywhere you set it up?
SOLVED: You can artificially create a 'meeting point'
The way they work now (up to 1.13) is that the iron golems spawn in a 16X6X16 block box around the geometric center of the village as determined by the positions of the valid doors if there are at least 10 villagers and 21 doors.
Bad news for technical players looking to move older worlds forward: all previous Fe farms and (probably) all villager breeders/farms etc are broken.
Bad news for the auto-farming opposition: building an Fe farm equivalent to a ~16 village farm (or 16 x 1 village farms) just became far cheaper and simpler (and probably more reliable)
Bad news for everyone: the high numbers of entities needed (~320 villagers for such a farm) make them quite laggy [Note docm77's complaints about tick speed and realize he plays on a top end box] thus further balkinizing the minecraft community [Along the lines of machine performance, as well as along the divide between 50+hour/week 'professional' players and the more casual masses that would prefer to be able to bring their worlds into the new version without large expenditures of time to rebuild.]
(This is, oddly, good news for the tutorial makes as the griefing of all/most previous designs will improve the demand/views of tutorials aimed at defeating the new mechanics.)
Re the OP questions directly:
While ilmango's video implies that a bell is necessary, docm77 makes clear that the bell functions only as a attractant to facilitate villager gossip. [Fe farms work via villager gossip mechanics which relates only rather indirectly to gathering points.]
From ilmango's video, it appears that the concept of a village as a 'thing' has been removed: villagers no longer have inside/outside village issues.
Iron farms (and villager breeders and villager-tech farms – assumingthe currently broken breeding and farming mechanics are fixed) can be built at any location.

WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
If anyone's planning doing any renovations to their 1.13 iron farm in 1.14 however, break all wooden doors in 1.13 first then upgrade, as there tends to be a glitch due to counting ticks that will shut down the game if you destroy previous iron farm doors in 1.14!!
Does that mean that breaking any 1.13 village doors at all in the snapshots can crash the game?
I wouldn't think the game would be able to tell the difference between an iron farm and a normal village.
I sure hope they fix that before 1.14 is released.
I don't know about a normal village but with my iron farm (Using a copy of the world naturally) it crashed every time I went to remove the doors!! I had to make sure every door was removed in the iron farm in 1.13 before then re-launching in 1.14 snapshots. Even just the 6 doors in my trading hall had a fit when I tried to remove them in a snapshot.
My villager trading hall would be a no-no as the amount of iron golems spawning was crazy!:
I had to lava bucket the lot in the end due to lag, 4 did survive somehow though! (Villagers)
At the iron farm in the lower section I glassed over the drop point into the cactus pit) (I use instead of lava) and iron golems still spawned below:
That said, in the farm in the floor above they also spawned and on the roof/around outside the entire building.
