By "work" I think you mean that if laser-focused on this one use case,
without a full implementation, it looks like it can work.

I'll give you a "maybe" on that.

But that leaves out the bigger picture. How many other things will we
regress doing this? What's the opportunity cost? What other things
will get neglected because we did _this_ one? Are there more users out
there?

Looking at the big picture, I'm not convinced those tradeoffs are good
ones (and you're not going to find anyone that's a bigger fan of pkeys
than me).
