Subject: Remove the only use of the CAG 'inherited_ro_instance' group
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=dbsrgits%2FDBIx-Class.git;a=commitdiff_plain;h=d2308dde5718dc0f828584c3fa24d7417c484040

Remove the only use of the CAG 'inherited_ro_instance' group

Introduced for reasons unknown back in 93405cf0, it is currently nothing but
baggage - especially given the lack of name synchronization as described in
one of the comments in 28ef9468

grep.cpan.me indicates no use in the wild, so just kill it with fire
