If you mess with some things there aren't gonna be launching issues. It can maybe also depend on some other factors but that's 99% of the crashes I gotNo? It's not supported, supported means there's no launching issues. That's all.
For blc I've found out it's sometimes based on luck too, sometimes I can inject without crashing and I sometimes can't.
Also I've got asked to test some bugs with blc/lunar (specifically 3rd party clients)
They do fix non working modules or severe issues, they added x ray in lunar back recently.
