I'm marking this as do-not-merge as I have not yet run device/sim tests locally. I had to nuke the world, so it's going to be a number of hours before they complete. I wanted to get this reviewed in Rolf's TZ. |

JIT (simulator) and interpreter (both sim and devices) needs IL to be present
In legacy the IL stripping is only done for
- device builds and
- release builds and
- AOT'ed assemblies (apps can mix and match AOT and interpreted assemblies)

wrt release builds I'm not 100% sure the debugger needs IL
However stripping takes extra time and does not help the debugging (on device) experience/flow

We only want this enabled by default when:
- Building with FullAOT, so:
- Not on macOS
- Not in the simulator
- Not when the interpreter is enabled
- Not on Mac Catalyst unless building for ARM64 and the interpreter is disabled (we can't JIT on Mac Catalyst/ARM64).
- Building for Release.
- Building with FullAOT, so:

We have a
_ParseBundlerArgumentstask that parses the extra mtouch/mmp arguments and writes the results to MSBuild properties:
https://github.com/xamarin/xamarin-macios/blob/f0373ee4f7140a70138fc919baf3fc3381656ef7/msbuild/Xamarin.Shared/Xamarin.Shared.targets#L1048-L1070
That task should be augmented to handle the --nostrip mtouch argument, and set this property accordingly.
