There’s a beta you can try using a test branch app on their staging servers, you’ll need to make a new account with your number again and there has been issues where its leaked your number

Not yet but it’s being worked on and it’s close now

Use a different homeserver for matrix and it’s way faster then the default matrix.org one for the element clients servers joinmatrix.org is a good list

Never torrent over Tor, torrent over I2P it actually supports it and has its own torrent client i2psnark

Depends which hard left, I know hard/far left people who hate them

its very much wanted, I dont want to have to create new accounts on every gitlab instance for all different projects like KDE, GNOME and others when I want to report a bug or something
