Note: communication disabled checks are a duplicate of #9730.

There is discussion in there on paths forward, but nothing has come of it (yet).

I'll add this issue as a related one

[vakiliner]

There is also a bug with Message.crosspostable that on non-community servers the message is not crossposted, but I don't know which guild feature to check (maybe News?)

[Jiralite]

Announcement channels can be used in non-community guilds (simply turn community off). It probably still allows publishes. That is something to test.

[vakiliner]

For v14, the ReadMessageHistory permission is checked in Message.pinnable, but not in v15

[vakiliner]

I found a new bug in Message.pinnable; in voice channels, this getter returns true, even though the voice channel doesn't support pins

[vakiliner]

Message.pinnable now checks the ReadMessageHistory permission and the voice channel!
