If we require an underscored _marid prefix to prevent potential collisions

I mean, if the underscore prefix is not widely deployed because few DNS
providers support it, then choosing an underscored prefix to avoid collision
leads to having to make world-wide changes to providers' User Interfaces, so
that the _marid prefic can be widely deployed; after which time you lost the
advantage again of not running the risk of collision.
I believe the reason for the underscore is that it is, in fact, NOT a valid
*hostname* character, but it IS valid in a domain name. It seems to be a
common, but incorrect, belief that DNS is only for hostnames.
