That requires PHB errata. If they were really comfortable with full-on PHB errata, do you think we would still be having official discussion of how people aren't happy with the Ranger six-plus years after launch?
As has been said, IIRC in this very thread, balance is a spectrum. No spectrum will please 100% of all possible audience members, but it is entirely possible to balance a structure so that it pleases most people most of the time. (I know people break out in goddamn hives when you mention video games and balance, but FFXIV does a fantastic job of balancing classes--they often miss the mark the first time, but within two patch cycles they tend to fix nearly all the problems.)
It is possible to fix this stuff in a way that makes things better without making them OMG DRAGONBORN MASTER RACE. I mean, even the Critical Role people knew Dragonborn needed a leg up, and they gave them one--both of the Wildemount Dragonborn subraces have a bonus feature that isn't overpowered, but has some neat applications. Is it as good as Half-Elf or even the basic Elf package without subrace? Eh...maybe not, but it's decent and that's all I can really ask for.
Agreed.
