Indeed, an awesome project and an excellent report!

Code size doesn't really get much attention, so the level of detail and the
strong roadmap is refreshing.

Hopefully, the project will provide execution times along with code-size

I doubt it.

Outlining will (almost?) always make for slower code due to a lot more
calls being made. But that's ok for embedded targets, that don't have
strong speculative machinery.

Also, if the program fits versus doesn't, then it will run infinitely
faster. :D

Kristof, do you know who at Arm would be good to review those patches?

cheers,
