Yep, smoke is not implemented (yet), rBASTdfa07e19cc35 just did it for fluids...
So cdef eModifierType_Smokesim = 31 and corresponding modifier_walker is still missing.
I could have a go at it (just started fiddeling with BAT and P732 is a start -- but needs further love [just pointcache, no OpenVDB, ...] -- also this suffers from the same glob vs. pathlib.Path.exists() issue as in T55007, T55539)
But before I continue, I would like to ask @Sybren A. Stüvel (sybren) if this is better placed on his desk?
Also this is probably not a bug, but a known limitation and more of a TODO?
