@sylvestre please review so we can get into 0.7.0. I will rebase to remove 5e269ff as the files are too big,

[oech3]

Do you really wan to merge this with current size? There are 2 Simulation perf regression.

[xtqqczze]

The main priority is to fix the test failures observed in #11081

[oech3]

Are big fixtures new test cases we were lacking?
