Delete FEATURE_INTERPRETER

[jkotas]

FEATURE_INTERPRETER is a poorly architected implementation of an interpreter. Proper interpreter implementation should start with a clean slate.

LGTM, thank you!

Is this because a new interpreter implementation is imminent?

There's also:

https://github.com/dotnet/runtime/blob/main/eng/pipelines/coreclr/clrinterpreter.yml

to delete. I couldn't find the actual pipeline in AzDO; it hasn't run for a while so maybe it got garbage collected.

Yes.

Could be interesting for mobile development. I heard of an experiment done at a former employer where the startup time of the (enormous) Java/Android app was actually faster in interpreted mode due to reduced I/O (... on some phones, mind you).
