add or remove emotes on the fly?
Persistence files allow you to save data which is subject to manipulation, but which needs to be available in case the mud restarts. Because .o files tend to contain information that is structured and formatted in a very specific way, they should never be edited by hand. They are intended to be loaded and saved by objects like daemons. Monkeying around with the contents of an .o file is an excellent way to damage your mud. Another reason to avoid it is that even if you make a valid change, it’s liable to be overwritten unless you fully understand the daemon that uses that file.
