rst-mode deprecated keybindings: okay to remove? During freeze?

[Daniel Colascione]

Would anyone mind terribly if I removed rst-mode's support for its 
"deprecated" keybindings? If not, can I do it before the next release? 
These bindings (e.g., C-c 3) have emitted warnings for years, and right 
now, they show up as ugly "??" entries in describe-mode output. I have a 
patch that makes the presentation nicer, but it'd be better to just kill 
these bindings entirely.
