As you say, easy to solve: agreed.

An open question and one we'd need to address: agreed.

I'm not entirely sure this is a problem.  If you're concerned about the
keyserver operator knowing that you're acquiring certificates, why would
you use that keyserver?  Why not use a different keyserver instead?  If
there were a single centralized keyserver, or a keyserver hierarchy
where individual nodes took marching orders from those above them, this
would be much more of a problem -- but here, the decentralized nature of
the keyserver network seems to work in our favor.
