So, why?  Is it because it has no defined inverse projection?  I think aitoff 
is another such, and it's not handled by GDAL either.

I see a +wktext option mentioned in ogr_srs_proj4.cpp:importFromProj4(), but it 
doesn't help.  I guess importFromProj4() looks at the projection and rejects 
the proj4 string before +wktext is helpful.

If I could figure out a WKT definition, does GDAL restrict that?

Any other way I can get GDAL to use wintri?
