GDAL adds the AUTHORITY node of the corresponding EPSG code.
this may be help #3191 (and maybe also other GIS software reading GRASS exported data).
also mentioned in a GDAL ML thread:
From what I can see the driver doesn't handle adding a new entry in the spatial_ref_sys table if there's no AUTHORITY node, such as in your use case. [...] Make sure a EPSG code is attached to the input dataset, or assign it explictly

Hmm... This is still an issue for me both in GRASS 7.4 (r72108) and GRASS 7.5 (r72157):
See also (sort of duplicate): #3048

In both cases gdalinfo shows:

That means:

AUTHORITY["EPSG","25833"]]
is still missing at the bottom of the CRS information, compared to CRS info with:

This affects interoperability with e.g. GeoServer/GeoNode or QGIS (https://issues.qgis.org/issues/14856).

It's a new feature, and EPSG codes should not be required in order to support custom coordinate reference systems.
