Yes it took me some time to fully grasp how the ZIL and SLOG worked and how it is not a cache.
There was some work done[1] on proper write-back cache for ZFS by Nexenta several years ago, but it seems it either stalled or there was a decision to keep it in-house as it hasn't made its way back to OpenZFS.
