Hello all
For information, a pull request has been submitted to the PROJ4J project
for adding GeoAPI wrappers in a `proj4j-geoapi` module. If accepted,
that optional module would be part of the PROJ4J project and deployed
together with PROJ4J releases, thus making easy to use PROJ4J behind
GeoAPI interfaces. The core PROJ4J module is unchanged, the GeoAPI
wrappers are optional.

Regarding the GeoAPI wrappers for GeoTools announced last Saturday, they
have been deployed on a Maven repository. It would have been more
convenient for users if that project was an optional module of GeoTools
like above-cited optional module of PROJ4J, but it would need to be a
request to GeoTools PMC coming from other volunteers than me (we would
be happy to donate the code to OSGeo). In the meantime, the Maven
coordinates are in the README file below:
https://github.com/Geomatys/geoapi-gt-wrappers
Therefore, the list of known GeoAPI implementations providing
referencing services is:
* Apache SIS (implements GeoAPI directly)
* GeoTools through `geoapi-geotools` wrappers
* PROJ4J through `proj4j-geoapi` wrappers
* PROJ through `PROJ-JNI` wrappers
* NetCDF UCAR library through `geoapi-netcdf-java` wrappers
