An important detail of this second point is that it sets it up on
function-key-map, which in the multi-tty branch is now made
terminal-local, IIUC.

Actually, I don't think that would be right either: when calling
xterm-mouse-mode, the user implicitly tells Emacs "trust me, this is
a terminal that understands the xterm-mouse protocol".  If you turn it into
a global (i.e. all terminal) mode, then it can break if some of the
terminals don't understand the xterm-mouse protocol.  I think
xterm-mouse-mode should not be global any more but terminal-local, so the
user would need to set it up for each and every terminal where she wants to
use it.
E.g., it should be possible to use xterm-mouse-mode and t-mouse-mode at
the same time.
