Veto duly noted, but:
1. I think those restrictions should be stated not in a comment in
svn.c, but in the documentation of svn_commit_callback2_t.
2. The commit callback can fail even when the commit succeeded, for
example, when stdout is redirected to a file on a full partition the
printf in svn/util.c will fail, or when a SIGINT occurs while the commit
callback is running. The client/wc layer needs to cope with these

I assume we agree that differences between RA layers should be minimal.

As I said, this is not only about post-commit FS processing errors but
also about post-commit hook errors.
% svnadmin create r
% ln -s /usr/bin/false r/hooks/post-commit
% svnmucc mkdir -U file://$PWD/r -mm $RANDOM

% echo $?
svn reports post-commit hook errors. svnmucc doesn't. Does either of
them need to be changed?
