All allied races we currently have use models and textures that were already in the game. You are at best talking about some hypothetical future.
Moreover, you are saying that you disagree that allied races are low effort, but then you are juxtaposing 1-2 regular races and 8-10 allied races. You are saying 8-10 allied races are more effort but if, say, at 6-7 allied races you'd say "it's about equal", then that's a definition of low effort even taking your hypotheticals at face value. When people are saying that allied races are low effort, they mean that a single allied race is much lower effort than a single traditional race. They are right in this and with the current allied races they are as right as 2+2=4 is correct.
I am not saying that allied races are a bad feature, they are a good feature. Easy content at next to no dev cost is good, they should pick low-hanging fruit like that left and right. But let's not make allied races something they are not, they are little more than a checkbox to play in NPC skins.
