Yes, this seems to be viable workaround. Absurd license, absurd solution.
We should clarify conditions for such distribution. I think that to build 
- GPL compatible GDAL
- GRASS linked to GPL compatible GDAL
- GPL incompatible GDAL
and distibute all on the same medium or on the same web site sould be OK,
or not?
What about installation, is it legal if installer automaticaly installs 
all components (GPL GDAL, GRASS, replace GPL GDAL by nonGPL GDAL)
in this order?

I completely agree, GRASS core must be free, preferably free and not Free,
but possibility to use non-free components is of the same importance.

Unfortunately import/export is not the only area where proprietary
applications would be desirable. For example, MrSID plugins are freely 
available for ArcView, Microstaion, Mapinfo, etc., why not d.sid for GRASS?
It is not too attractive to tell people, currently using MrSID, that
they can use Free GRASS, but they have to buy 20 new hard drives for data.
