Don’t forget that the guidance on ground gas protection is based on the idea of multiple levels of protection and redundancy specifically to deal with the issues of what happens in future. This starts with the underfloor venting - blocking up a significant proportion of the vents should not compromise the safety of the system as the design (yes - there should be a design) should have a suitable factor of safety.
If the venting is completely prevented - there should be a gas resistant membrane to prevent ingress into the building - installed and verified correctly.

Hi David
I'd go for the restrictive covenant, as this explicitly places a responsibility on the owner and warns them in the process. If they then do something to prevent underfloor ventilation, then on their head be it. This may sound harsh but consider a scenario whereby someone has a gas heater fitted, this is much more common and dangerous, but you would not inspect the flue annually.
You can never legislate against stupid.
