Results in weak, suboptimal builds.
No it doesn't.
I don't think I've ever played a class/race combo where the strong ability score has aligned with the key class ability score, and I've played with plenty of players who, conversely, do put a lot of stock in that... and I have never felt weak, sub-optimal or less functionally effective than other characters.

Can you say the same for cases where
neither racial asi has aligned with a key class ability score (or Dex)? [70% curious, 30% gotcha]
I.e., a half-orc (+2 Str/+1 Con) or Tortle (+2 Str/+1 Wis) Wizard
or a Gith (+1 Int/+2 Str or Wis) Bard or Socerer?
