The grass --help does not mention support for "Proj" strings. Only
geo(-referenced)file and EPSG.

Usage:
  grass75 [-h | -help | --help | --h] [-v | --version]
          [-c | -c geofile | -c EPSG:code[:datum_trans]]
          [-e] [-f] [-text | -gtext | -gui] [--config param]
          [[[GISDBASE/]LOCATION_NAME/]MAPSET]
  grass75 [FLAG]... GISDBASE/LOCATION_NAME/MAPSET --exec EXECUTABLE [EPARAM]...
  grass75 -c [geofile | EPSG] --tmp-location --exec EXECUTABLE [EPARAM]...
