Default spam whitelist option compatibility with spamc

I have recently discovered a possible bug on a server.
On this server, some domains were using spamc while others were using standalone spamassassin.
For logging purposes, I decided to switch all domains to spamc.
Everything seems to be working just fine, but on the scheduled automatic validation, I received this warning:
Whitelisting of all mailboxes in each domain is enabled on the Virtualmin Configuration page, but this is incompatible with the use of the spamc SpamAssassin client program

This setting was enabled from start and was working just fine with some domains using spamc while others the standalone one and I never received any validation warnings

Is this warning still valid?

later edit: it is still valid. Whitelists are not working.
For some reason, the validation only warns when ALL domains use spamc, so I still think this is a bug in validation.
