Quite the opposite, IMHO.

It cannot possibly be worse than the current abuse of the post-command-hook
to do all sorts of things that would be better done by specific hooks like:


post-switch-buffer-hook  (when last command switched buffers)
post-switch-window-hook  (when last command switched windows)
post-modify-buffer-hook  (when last command modified selected buffer)


I'm pretty sure there are modes which uses various post-command-hook 
tricks to accomplish the equivalent of these hooks.
