A lot of what you described is exactly why we have the Progressing Hacks section. The Launchpad isn't necessarily meant for people who have made progress on a hack, either in the present or the past. There are a lot of people who discover the magic of romhacking and immediately want to share their ideas, good or bad, with everyone else. The Launchpad exists to give people an outlet to do so, even if nothing comes of a lot of the hacks there.
In terms of what you suggested for Discord, can you elaborate on what you mean a little bit?
