i would still like to understand how object proxying (e.g., weakrefs, RPyC), could work when all/most frameworks/libraries would be based on ABCs.

That's a realy problem. zope.interface works hard to deal with proxies, but it probably only works with proxies based on zope.proxy.

the only way out of this, that i can think of, would require introducing a does_implement special method that will be called by does_implement(), or whatever the name will be. of course you could add a new ABC for that purpose, i.e., CustomImplementer.

This only works if there's only one interface system. As soon as there are multiple systems at work in parallel (possibly because different libraries require them, even if the app doesn't care), this is going to get quite complex.

I wish I had some good insight on how to deal with this, but I don't. Jim Fulton might have some ideas since he dealt with all this for zope.interface.
He's likely pretty busy right now, though. (And I don't know if he's on this list.)
