This seems to be what was responsible for the change:

commit 599ca626d760215b090012c69c749d391cfd6fbe
Author: Stefan Monnier <address@hidden>
Date:   Wed Mar 25 09:47:12 2015 -0400

    `save-excursion' does not save&restore the mark any more

Searching the emacs-devel mailing-list archives for
`save-mark-and-excursion' I don't find any discussion
about introducing it.  I find only an occurrence that
mentions that commit:

http://lists.gnu.org/archive/html/emacs-devel/2015-12/msg01596.html

Searching the bug list I find only two occurrences,
which are from the year after that 2015 commit.
