the point is for new players to start out a simple contraption since its impossible to teach new players when they simply break it, or do something wrong. if you dont like it, fine, would it be fine if you met someone who didnt know redstone, and they need a simple way to learn. The redstone paste would be useful and could also make large contraptions as well
As a programmer with over 30 years of experience in multiple assembly languages, java, and other languages I support anything that is "elegant". This is elegant.
It is irritating when a pretty building has to be bloated to fit in redstone. Redstone could be much more elegant than it is.
There should be another crafting level in redstone and you should be able to place repeaters and comparators without requiring a supporting block.
the electric wires on an electric pole or transformer holds the wire in place, so i dont think redstone needs a support block all the time, and a support block can still be in effect, Plus if there is a griefer on a server and they destroy the contraption you just built. then you will waste your time fixing it because redstone can't float on air right now
