No problem, what Majestyc2k1 said is very true and relevant, but for me I just stated what I've experienced in the last few years as a player (1.7.1 to 1.14.4 have been the good years of experiencing modding for me). From hearing what devs say in the Rift & Fabric Discords as assisting players with installs (in the last year and still every so often).
To noticing who worked on Forge aspects in the changelogs.
To just watching interviews with the devs on GreenPhelm's YouTube here: https://www.youtube.com/playlist?list=PLCnnzO1tiQZzI0yjleCCKsQwIUL9ULbMu,
Not seen many of the ones from this next playlist link as they are more from years ago compared to devs still around that make the major mods and do things with Forge like the first playlist: https://www.youtube.com/playlist?list=PLCnnzO1tiQZyq-Lv2sDwhRyxKGOcc_YKj
So I don't have accuracy for all things as I'm not a true dev myself (I understand code but I do proper modding/know much about Java coding compared to other code) but while some info is second hand, the rest is guessing based on what seems likely.
