Jason Dillon commented on GSHELL-34:
------------------------------------
The purpose was to hook up a few custom url handlers to support vfs urls and
rfile (remote-file) urls, so that when connected to a remote shell one can
access local files (remote files on the client). I can disable it for now,
since I've not yet finished the rfile bits.
