When will try_recv be added back?

[UE2020]

#3263 (comment)

The mpsc try_recv() functions have an issue where a sent message
happens-before a call to try_recv() but try_recv() returns None.
Fixing this is non-trivial, so the function is removed for 1.0. When the
bug is fixed, the function can be added back.

When will try_recv be added back?

When I find the time to properly review #3639. It's not been my top priority, and is relatively complex.
