That's not a problem with most/all Feats at all.
It's a problem with a specific subcategory of Feats, and it's been a huge problem since 3E. I call this category "enabling Feats", but that's an overly positive name honestly lol.
These are the Feats where the thing the Feat lets you do should either be:
A) Something that the game should routinely have rules for, and it's dumb that it doesn't - like Charger.
or
B) Something that the DM might give out at their discretion, and that's probably an unusual situation, but because Feat exists, the implication is it can only happen with the Feat.
3.XE was absolutely top-to-bottom riddled with Feats like this, and Feats which were "Yeah you can do X but you'll be absolutely rubbish at it unless you have this Feat", so I get where you're coming from with those. But most Feats aren't these, especially not in 5E, which actively set out to avoid that.
No lol, an excellent argument to not allow THOSE SPECIFIC Feats, which are a minority of Feats in 5E - they might have been a majority in 3.XE, and even if they weren't, there were huge numbers of them, whereas we could easily go through 5E and call out every Feat which was like this, and I don't think we'd even get to 10.
