Yep, it's extremely annoying, no doubt.
I've been that guy - I am that guy. The kind of person who's worried about desktop litter and always uninstalls a utility from his PC after I'm done with it, if I don't think I'll be using it frequently. I always wait years and years before upgrading to a new version of Windows. I was the kid who defragged his hard drive daily, back in the days when that still mattered. So I understand the appeal of having a set-up that works for you and not wanting to stray from it.
But lots of people aren't like that, and things do always eventually change, so I don't know...I think it's wise to be dispassionate about things and see what happens. If it turns out people aren't willing to use the Epic Games Store, the game will suffer commercially and the free market will do its job.
