Polluted Dirt not emitting Polluted Oxygen at the right rate

Since Mergedown happened, Polluted Dirt doesn't offgas at the right rate: it's incredibly slow, and prevents setups relying on it from working (clay and oxygen making).

This bug was already reported a few days after Mergedown happened but is still current:

It's a mechanism change that makes absolutely no sense in vanilla (because Polluted Dirt tiles don't exist), unless the Sublimaton Station is made available to vanilla.

Can the Polluted Dirt offgassing rate be reverted to it's pre-mergedown value, or at least the Sublimaton Station made available to vanilla?
