No, he's wishing he could enforce it. Which will work, mostly, until
the day it doesn't because of a pre-existing collision. And then he'll
be up the creek with a lot of software that he can't fix readily. I
concur with Andrew's advice: don't go there in the first place. Use a
cache to mitigate the costs of looking up user-defined OIDs, and you
won't regret it later.
