Basically currently the proof format of Z3 has bugs that we cannot solve on the Isabelle side ( Fixing those requires either internal Z3 knowledge or time from a Z3 developer.

Additionally, Nikolaj Bjorner is reworking the proof format. Currently it looks like a lot more work on the Isabelle side (trimming the proof). Also handling of inprocessing is not clear yet.

Not ready for the Isabelle2021-1 release, approx. 15-Dec-2021. Note that veriT is more and more taking over.
