I can follow that the Zil does not add more fragmentation to the free
space but is this effect relevant?
If a ZIL pre-allocates say 4G and the remaining fragmented poolsize for
regular writes is 12T

A slog helps fragmentation because the space for ZIL is pre-allocated based on
a prediction of
how big the write will be. The pre-allocated space includes a
physical-block-sized chain block for the
ZIL. An 8k write can allocate 12k for the ZIL entry that is freed when the txg
commits. Thus, a
