Yes.

Note that the command line pseudo-filename's URI syntax stays the same
(file=gluster+tcp://), and the command line's dotted key syntax keeps
accepting tcp for compatiblity (file.server.0.type=tcp works in addition
to =inet).

I'll cook something up.

This is where I keep file.server.N.type=tcp working.

Will fix.
