That's pretty unfortunate.

Not at the moment, but given the situation it really does strike me as
something we want to solve. Inventing an ID would likely be overkill
or wouldn't solve the problem anyway, I'm guessing...

I definitely think it's worth it, even if it doesn't handle an
inline-compressed datum. PostGIS is certainly a good use case for why,
but I doubt it's the only one.
