A server will have to respond with an error to requests that reference
something (e.g., a datastore) that does not exist on that particular
server. While 'conventional' likely never exists as a datastore, you
sill have to check for the datastores actually supported by your
implementation so the check for 'conventional' likely falls out for
free anyway.
