Care to elaborate?  Do we have a better proposal?  Or even just some rough ideas?

Or could we rebuild the core libraries and define new API's (for 5.1? though
probably slightly longer term), then provide wrappers around the new code so
existing commands don't break?  Should be possible for at least part of the
library, such as the catalogue services and region of interest - though as a
newbie to grass I could well be wrong about that ;-)

Just a thought :-)
