mod_muc_markers: Prevent any markers from reaching the archive, even if untracked Original intention was to leave alone things that this module isn't handling. However markers in archives are just problematic without more advanced logic about what is markable and what is not. It also requires a more advanced query in mod_muc_rai to determine the latest markable message instead of the latest archived message. I'd rather keep the "is archivable" and "is markable" definition the same for simplicity. I don't want to introduce yet another set of rules for no reason. No markers in MAM.
