One important reason against it is, that it makes uses of the mark ring
other than marking text very unpleasant. The manual starts section 12.6
with the example of using the mark to mark interesting spots in an
buffer so that one can easily jump between them (in many cases this is
faster than saving positions in registers and therefor very
convenient). In such cases the highlighting of text between point and
the last mark is distracting and useless.
