It can be good for certain builds, but in practice 2-3 of those +1s end up being meaningless for most characters, and with the Tasha's changes, every character can freely distribute +1/1/1 or +2/1, making it a wash in almost every case, including on Vumans who can pick up an additional +1 from the feat. Between that and only getting one floating skill proficiency when most heritages get a fixed or small list skill proficiency in addition to one or more standout features, base human is by far the weakest choice.

I think giving a feat, a skill and an expertise would be a good way to set them apart a little bit from the other heritages.
