The current implementation effort publicly started 2017-10-27. For a
major feature that's really not that long ago. There also were a few
gaps in which no public development/discussion happened.

I'm not sure there was agreement on the design even. A lot of that has
been discussed until very recently.

I think the implementation at the least should be roughly ready, and
implement a roughly agreed upon design. It's fine to change things
around, but major re-engineering surely is an alarm sign.
