Because lots of markers degrade Emacs regex search performance
tremendously.
See https://list.orgmode.org/orgmode/scedec$2g0$1@ciao.gmane.io/

The situation is third-party code doing bloody murder with
(with-silent-modifications
(insert "Some text not triggering modification hooks))
Another scenario is modifying text in indirect buffers created with
make-indirect-buffer. (where there is no chance to install
before/after-change-functions via clone-indirect-buffer-hook).
