Perhaps it would be worthwhile to have extended ops be implemented
by a helper binary for such extended purposes ("svnstat"? "svnanalyze"?).
That way one would not bloat the usual hotpath workhorse binary with such...
shenanigans :)
(both in performance terms and in usability terms - usage text length...)

But that decision probably depends on the total number of conceivable
"extended" ops. If there's only few high-level op names
which do all the work and options internally,
then one could keep them provided by svn, else...

But keeping them in main binary might still influence overall performance -
unless implementation data of commands
(as possibly opposed to registration data of commands!)
is being provided on-demand only anyway, via shared library dlopen references.

OTOH you could argue that the total amount of SCM sub commands will ultimately
remain limited, thus it's better to keep them aggregated to main binary
and do maximum optimization of that case instead (dlopen etc.).

E.g. git (Jehovah! ;) seems to be doing it that way, and with
external git_load_dirs binary being analogous to svn_load_dirs binary to boot.

Apologies for the long rambling - I had expected it to remain shorter,
but then with all the details added...
