It’s extremely relevant. The main issue is what level of scrutiny is required for gender based discrimination in education? If you accept the majority’s view in the VMI case that an exceedingly persuasive justification is needed, the next question becomes can discriminating in admissions on the basis of gender meet that threshold? You would need smarter legal minds than mine to look at the issue, but my sense is explicit gender quotas would likely be unconstitutional, at least in so far as we’re discussing public colleges(assuming you accept the level of scrutiny in the VMI majority).
