I think the branch scratch/igc has now reached the same state as in my
local Emacs, unless I'm overlooking something of course. To quote myself
up-thread:

  If someone doesn't remember what MPS is about: concurrent, incremental,
  generational, mostly-copying, thread-safe GC.

  I've now reached the point that I wanted to reach to consider my
  experiment of using MPS in Emacs successful.

  - Emacs builds from scratch
  - Tests succeed to a sufficient degree
  - Emacs starts in GUI mode

  That's all. There is nothing more. And I'm currently undecided how to
  proceed with this.

Please note that I'm using macOS only. Can't say anything about other
platforms.
