Over correction does already happen (not sure if you meant you haven't yet observed over correction, or the negative fallout of it). See for example Glowforge's approach: https://glowforge.com/blog/at-glowforge-we-pay-for-diversity...

While I absolutely wish that any person felt welcome in tech regardless of race, gender or other choices like orientation, I'm not convinced this is a good approach. It's an explicit statement that they are desperate for diversity, and as a result it calls in to question the justification for those hires. How much did the candidates diversity factor in vs. their competence?

They claim that non-minorities won't be disadvantaged by them and I believe they are being honest here, but it still sends a very mixed message.
