Yes, Mozilla discourages redundant mrows; but, no, they do not cause
real harm, and they are sometimes a necessary side effect of automatic
translation from an author-level markup to XHTML+MathML.

This is a controversial matter; please do not pretend otherwise.

In mathematics juxtaposition usually has a default meaning as an
operation that is context-dependent.

With presentation markup it is a matter for the author (and
the editor) to settle so long as the document is valid.

If an author does not want to use &invisibleTimes, the effect
of labeling his/her markup wrong is to drive him/her away from
placing XHTML+MathML content on the web.  Is that what we want?

Finally, one should observe that "mistakes" in the output of a
translating program are not necessarily the fault of that program;
they may be the result of quirky or incorrect input.
