I am very much looking forward to v1.22. Inlining was/ is one of the Achilles' heel of Go (and other languages).

There's a good issue (#21536) which explores possible ways to implement explicit inlining. Sadly, the proposal got closed without any change.

I wonder why they're doing it – it's just bull crap to close any account having more than one game purchased.

Do you experience problems with Element (the Client) or with Matrix? And what types of problems do you encounter?

I don't understand whether you want another platform or another client to use Matrix – from my perspective, it would be the best to report those problems.
