masking LDAP_SIZELIMIT_EXCEEDED

I've found a situation similar to what I believe inspired "disclose" ACLs, in which giving out the return value of LDAP_SIZELIMIT_EXCEEDED is telling clients something that I don't want them to know (i.e. "keep digging.") I'd like to just throw away the code and change it to LDAP_SUCCESS. Can anybody think of a way to do this (slapo-retcode comes to mind, but I can't see how it would work on these very non-dynamic entries) or should I just write an eight line overlay?

Is this something that enough people want that there should be, say, a "silent" option to the limits directive?
