[PROJ] Alternative PROJJSON implementations?

[Even Rouault]

Hi,

A pure Python PROJJSON (not using pyproj) to WKT2 converter in 
https://github.com/rouault/projjson_to_wkt

And a Javascript port of it in https://github.com/m-mohr/projjson_to_wkt

One question that came up in our discussion is whether or not there are any alternative software implementations of PROJJSON besides PROJ's itself. Did you write one? Are you using PROJJSON in commercial or open source software that isn't PROJ-based? Is forward/backward compatibility of PROJJSON a priority for you? Information about these questions would be useful for us to know regarding possible enhancement or evolution of PROJJSON going forward.
