You seem to be replacing a "meets or exceeds" requirement with a
"strictly meets" requirement.

I'd suggest something along the lines of
The CA MUST use one of the allowed methods of domain validation
(<insert reference to the 10 Blessed Methods here>) and, in addition,
MAY use additional and/or stricter methods of domain validation.

In other words, make it clear to an auditor that while the CA must
meet the baseline requirements, it's not an audit failure if they go
above & beyond the minimum requirements of domain validation.
