Since the type code is a 16-bit field, if we allocate a new type every week, it'll take over a thousand years to run out.

We don’t know exactly what the future will bring.
Uh, what? In the past 30 years we've assigned under 100 rrtypes. If that rate increases by an order of magnitude, we still have a thousand years of them. Sure we don't know exactly what the future will bring, but we can make some reasonable guesses.
I do know that saying that classes can’t work is self defeating and will take a lot, lot, lot more of work to undo than just continuing to support multiple classes.
Classes were a mistake. We should deprecate every class except IN, perhaps keeping the one special case for CH server.bind. That doesn't require changing any of the bits on the wire.
