Well, for starters, Luke has been consistently right about most things in Bitcoin, while Vitalik has spent the last 10 years making all the wrong calls - only to recently admit he screwed up almost every step of the way. That said, none of this is a reason to blindly trust Luke or anyone else.

But circling back to the current situation: some of the newer Core maintainers are now proposing changes to client features that have been part of Bitcoin since 2014 - features with a near-perfect track record of efficiency. That alone should raise serious concerns, alarm bells, and doubt in the minds of anyone with two brain cells.
