I thought the demons and devils served demon lords and devil princes. Seems a bit odd that good gods get their own, special servitors, but, evil goods get Asmodeus' leftovers.
If you think evil gods don't get their own galaxy of supporting supernatural beings, you didn't read the half of my post wherein I described undead as filling that role in general in D&D, regardless of if the god's LE, CE, or NE. LE gods can also sometimes get devils, too. It's like the cherry on top of the evil cake.
Additionally, just because balors serve demon lords doesn't mean that some don't also serve deities, and just because pit fiends serve Asmodeus doesn't mean that some don't also serve deities, and that's been a core part of their existence of demons and devils from early on in this game, too. I can draw another Venn diagram, if that helps.
So, according to the canon you want to preserve, demons most certainly do not serve CE gods. Or is the wiki mistaken?
If you think that's what the wiki article says, you didn't read the very sentence you highlighted. This particular kind of demon serves Lolth very intimately, and, it is implied, other demons also serve other gods, just not necessarily so intimately. Meaning, in other words, that while yochlol are found specifically and almost exclusively under Lolth's guideance, balors (or whatever) can be found in the service of any CE god, or even independent of the gods.
So, are we agreed? Evil gods don't really need a splinter group of yugoloths to serve them, since they have plenty of other things to serve them, including specialized servitors, demons, devils, and undead. Decades of D&D have gone by with no one really lacking for servants of evil deities.
Glad we've come to an accord on the "lets not change yugoloths categorically to become the servants of evil deities," at least.

Why would I get a dragon with a gate spell? Why would I get Undead with a gate spell? I mean, if you're going to get all technical about the mechanics, at least have the decency to read the spell first. It calls an extraplanar creature. Neither dragons nor undead are generally extra-planar.
Well, first of all, you're assumption that dragons and undead aren't extraplanar is false. Any creature can be an extraplanar creature. Just needs to be on a different plane. A gold dragon hanging out in Bahamut's court? A lich who lives in Vecna's home?
There's also the magic of templates in the last edition the
Gate spell appeared in.
Bahamutite could also get a celestial gold dragon.
Vecnite could also get a fiendish vampire.
Since they're high enough level to cast
Gate, they might be able to even get an avatar.
Demons are just one kind of thing you can call on.
