why not? the alpha channel can just be thresholded at 128 and a mask generated.
not to mention as an example - e17 runs on that hw just fine.. with alpha
channeled compositied icons and graphics all over. alpha blendind did exist
well before xrender - and doing it in software client-side is still by far the
fastest way to do it in general - modern xrender extension or not. so i think
it still stands to reason that providing the information that way is valid. HOw
you chose to display such data is still an open descision on the part of the
toolkit/tray manager etc.

specifying a netwm specification thet REQUIRES an extension that may or may not
be supported and if it is supported still is od dubious quality i think is bad.
if the specification does not rely on an extension and leaves that up to a
descision of the toolkit used for display - then you haven't created any extra
