wouldn't be enough just to give the epsg number or a proj4 string that PROJ could deal with it?
yes, the ProjectedCSTypeGeoKey key is for that purpose. Cf https://docs.ogc.org/is/19-008r4/19-008r4.html#_requirements_class_projectedcrsgeokey and

HI,
(Sorry this is not an issue but a question..)
I want to use PROJ to re-project some .tiff layers, And there are so many geoKeys to define the projection. wouldn't be enough just to give the epsg number or a proj4 string that PROJ could deal with it?
Regards and thanks for all your work!
