Agreed - no java where not necessary.

But PyWPS is python, which is already used widely in QGIS and GRASS.

Definitely - I haven't used the GRASS plugin for some time, but I see
it as an important aspect of QGIS. If it is not working nicely at the
moment, it should be fixed - no questions.

Nevertheless, I would suggest that for the future (mid term) the
possibility of replacing the GRASS plugin with WPS technology might be
the way forward, as it should open the possibilities to interface with
other WPS compliant applications as well.
