I think that would be a good idea, at least for posterity.  So please
do.

If so, then (assuming we decide to accept this change), the name of
the command should be something like kill-word-dwim, and the doc
string should mention the two commands you refer to above.

Any reason why you need this command and cannot settle for the two
commands it replaces heuristically?  Are you using Emacs with
transient-mark-mode on or off?
