Most of the tools are part of OGGM anyway, and the job for RGI was done in rgi_scripts.
There would be some advantage in moving some RGI scripts to an independent package (like https://github.com/ezwelty/rgi_links) but time is missing to clean all that up before RGI release...
What's certain is that RGITOPO will move to the OGGM domain, that's just much easier to maintain there (and is an OGGM product after all...)
