Unless you constantly play more than 6 hours straight without rest, the mediocre battery of PS5 controller is not really a problem. Much less so if you have the official charging dock.
I know, it's not a huge deal, but buying a separate dock, or dealing with yet another thing to charge all the time is annoying. So personally I prefer longer battery life over a bunch of fancy features that are likely only going to be used in Playstation exclusives.
I have more than 10 controllers spanning most gaming systems, the only one that consistently runs out while playing is the ps5 one. They could have added a few more 100mAs to make it tolerable :(
