@vyr @tobi You run the TypeScript compiler on the codebase and it throws a few thousand typing errors (but compiles anyway??)
The frontend in particular seems to be a tangled pile of soup.
And most of the forks are hard-forks of Misskey 12 so they can’t just pull things from upstream; everything has to be done from scratch, and the few developers with experience on the codebase are spread across four projects these days.
