I don't think so, or I'd have added a note to the upstream README when
I committed the _arguments change upstream.  The interface between
_arguments and comparguments is an implementation detail with minimal
user-facing documentation.

Thanks for fully-fledging that link ☺

Correct.  The interface between completion functions and the completion
system (e.g., between _git or _curl on the one hand and _files or
_arguments on the other) _is_ an API with compatibility promises.
The interface between _arguments and comparguments, on the other hand,
is an implementation detail, so they should be upgraded in lockstep.
