Anyone come across these guys? https://potatosemi.com/

They look to have some very fast 3v logic - though not yet full 74 families. No idea about availability or price, mind

What's an additional VIA among friends, anyhow?

Don't see why; they're Taiwan based but appear to have a US presence. I have no problem from Germany.

They load HTTP content even if you accessed it via https; your browser might block this "mixed content" because of security reasons. At least, mine does.

That's why the link without https works: http://potatosemi.com/

They don't seem to have any counters listed unless you chain a bunch of DFFs. They list a max prop delay of 2ns for those from CLK to Q, so if chained and running at GHz speeds you'll be counting propagation delays in dozens of cycles. At that point I imagine you'd have to design skew-tolerant logic rather than try to avoid skew entirely.
