I would suggest that you file an enhancement request, via `M-x
report-emacs-bug'. The Emacs developers will then DTRT (decide whether and where
to enhance Emacs for this).
IMO, there should be a user option that controls what "whitespace" is affected
by this and similar commands (e.g. `fixup-whitespace',
`delete-trailing-whitespace', `delete-blank-lines').
And modes and other functions should feel free to bind that option when (they
are sure it is truly) appropriate.
[Yes, I know that some consider it heresy to allow/endorse Lisp binding of user
options. I do not. Sometimes it makes sense for a function to control an option
value, but yes of course, generally the user knows best. If it is problematic
for some given option/context, then value choices can be provided for both
possibilities - some values inform programs not to override/bind. E.g., if
non-nil (or whatever), then just bind to the existing value (essentially a
no-op), respecting the user choice, else do something the program considers more
appropriate.]
