The speedbar is created with the same height as the attached frame.  For
sure you would also want to synchronize their heights in the event of a
resize?  (And not only if the main frame is resized from the top edge,
of course.)

What if the “precise location” is stipulated relative to the bottom
right corner of the frame?  I wish I could stick a clock at the bottom
right of the main frame, as if it was part of the echo area but right
aligned.

Any of the things above can be achieve by adding the same function to
both 'move-frame-functions' and 'window-size-change-functions', but that
indeed seems to much noise.

Resizing a frame is just as rare as moving it, and much less common than
changing window configurations, so I don't understand the concern.
