import P.Q (1) from P.Q import X (2)

would only look for P in sys.path (I'll call this "absolute import"); and from ...P.Q import X (3) would scan for P upwards from the current package. I think this addresses all the concerns I've seen brought up in this thread so far

No, it doesn't address my concern that scan-upwards semantics should be the default, in the sense of being what should be used in the absence of a reason to do otherwise, and should therefore have the most straightforward syntax.

Also, you don't seem to have anything for the explicitly-relative case, which might not be strictly necessary, but I think I'd feel more comfortable if it were available somehow.

Thinking about the double_underscore names, it might not be so bad if they were a bit shorter, e.g.

A: root.P.Q B: here.P.Q here.parent.P.Q C: P.Q
