Huh. I was just about to make a post complaining about how my maxed-out stealth character can't sneak past them. Surprised YUP hasn't fixed this, tbh. They've made more intrusive changes than this trying to second-guess the devs' intentions.
Speaking of Dead Money, I never understood the timing of the events leading up to the Great War. Dean says in conversation that he introduced Keyes to Sinclair,and he built the whole place for her.

Especially since he bankrupted himself in the process.
Even the Wiki page on Sinclair directly contradicts itself in two consecutive paragraphs (emphasis mine):
Just a nitpick, but it just always bugged me.
