User Pref to not overwrite Recent Files list everytime you open a new
file

This is just a more formalised version of a local hack I've been
running locally for the past year now. It's especially useful when you
want to maintain your own set of recently opened test files (or
perhaps current project files), but then be able to quickly open some
.blend files downloaded from the web (i.e. checking out some bug
report, or how someone else sets up some node setup) without
loosing/polluting your existing recent files list as a result of doing
so, and having to either resort to some nasty methods to get it back.

Of course, this is still really hacky, as for instance, it means that
the currently opened file will not show up in the recent files list
for quick reload. However, that's why this is a userpref :)
