[Geotiff] "standards" process?

In both libgeotiff (and also embedded in GDAL),  there appears to be a "canonical" encoding for the various supported projections. Can anyone comment on how those standards (or conventions perhaps) came to be, and more importantly, what the process might be for extending them?

I have commented here before that I believe the convention for polar stereographic is not quite correct (link below), and am further interested in seeing support added what proj4 calls the "General Oblique Transformation" (proj=ob_tran) added.  I'm prepared to provide a fix for the former (assuming everyone/anyone agrees its a bug), and a proposal for the later, but how best to proceed?
