Reminds me of how they incorporated weapon type-specific attacks in BG3. Stealing this one for sure.
Yep, that whole weapon maneuvers system should be backported into base 5e stat, with slight modifications (i.e. they would be PB/LR instead of 1/SR, since short rests in the tabletop version are less regulated).
(Or alternatively they could auto-proc on a crit.)
