I try it again: Imagine you are searching your projects (because you don't know what idea hides behind a cryptic filename, you're searching for a special passage or just want to listen to them). You can do that via filemanager without leaving traces unrelated to your actual work. Or imagine you fire up an empty project to test something quickly, wouldn't you hate it when this displaces the project you were working on 5 minutes ago and you want to continue working on in 5 minutes, making you browse to that project instead of just clicking the normal Reaper desktop shortcut? The way it is now, you have a choice what gets remembered (without introducing yet another option) just by choosing how you open it. Removing this would be "dumbing down" the behavior IMO, whatever you touch gets remembered even if you don't want to. I assume it needs additional code to make an exception for the "recent..." list so that wild opening of projects wouldn't mess it up.
