In reply to Tammie Lister.

Matt has been adamant in saying that Gutenberg would not be merged into core unless he and the team decided it was ready. It needs way more testers/testing. Optimistically, the merge proposal would have happened with 5.0 near the end of this year but now we know that 5.0 is the target version for Gutenberg and it won't happen without it. Both are pushed back to next year.
