Not sure, but for what I know the srs.db is generated with a script
using the same as or maybe the proj-db.
We discussed about changing stuff but I thought we came to the
conclusion to not let users/devs change this workflow. Otherwise we
would end up with non-compatible definitions by different tools.

Don't know about how gdal uses proj-info. Best to ask on the gdal list.
