For what it's worth, I never thought that ... but it's likely
a defensible policy, in conjunction with other policies.

Thing is, wakeup is also a runtime PM mechanism, not just a way
to kick a system out of a sleep mode.  In fact, a "sleep mode" is
just a point on the spectrum of runtime power saving modes, so to
reserve one exit mechanism for sleep modes seems like a strange
concept:  drawing arbitrary (and not that useful) lines in the sand,
which make it hard to package a coherent/unified approach.
