I hope to analyze and reply in depth to your message later but that
leapt out at me.

I see no reason to modify arch in the slightest little bit to solve
*that* problem.  Surely it can be solved more cleanly with proxies.
In many or most cases, simply using the existing mirror functionality
more carefully is sufficient.  It is strange, imo, to contemplate
modifying tla to solve the problem you stated there.

A "smart cache" in arch would, as a side effect, very likely anyway,
eliminate the need for an external solution (while accomplishing much
else besides).  But that is just a happy accident, I think --- and one
that we could useful give up on if it were convenient to do so.

The way to build a "smart cache" is top-down, not bottom up.
Meanwhile, tla shouldn't have a built in "dumb cache" when it so easy
to construct one externally to tla.
