is portmaster --check-port-dbdir obsolete?

[Anton Shterenlikht]

With ports tree at r322480, I updated
several ports with portmaster.

"pkg check -srda" did not find any problems, but


# portmaster --check-port-dbdir
===>>> Building list of installed port names

===>>> Checking /var/db/ports
        ===>>> devel_apr1 does not seem to be installed

        ===>>> Delete /var/db/ports/devel_apr1? y/n [n] 


        ===>>> math_gmp does not seem to be installed

        ===>>> Delete /var/db/ports/math_gmp? y/n [n] 


        ===>>> www_serf does not seem to be installed

        ===>>> Delete /var/db/ports/www_serf? y/n [n]

So is "portmaster --check-port-dbdir" an obsolete check?
If so, will this option be removed in future versions?
