I also don't like them stubbornly making everything a Bonus Action just to get more actions per turn. But if they absolutely must insist on staying on that path I'd rather they would come up with something like Bonus Weapon Abilities than making stuff like Hide and Shove a BA for everyone and breaking the game.
I would like to try Pommel Strike as an unlimited action with proper balancing. Trading damage for a status effect feels like a real tactical choice. But with Stun I do smell a potential problem in a 3v1 situation or an 11th level Fighter spamming up to 3 Pommel Strikes per turn to stun-lock a target. Pommel Strike's Daze is now Disadvantage on Wis Saving Throws, no reactions and lose Dex Bonus to AC for 2 turns. Pretty powerful already and crippling for Dex classes. But the Wis debuff is really cool. Pommel Strike > Hold Person would be fun. I guess they'd just have to do a lot of balancing.
