Thanks! Sending the bug through triage to verify the exact behavior we want (see #5659 (comment)). I think your PR is the right behavior, but it is a breaking change.

[StephenWeatherford]

Requested some changes. Also awaiting decision from triage on desired behavior.

Looking great! Only one remaining item... We need testcases for the new functionality. I'd suggested adding the following two scenarios to. DecompileCommandTests.cs:

Decompile_OutputFileExists_ShouldFail
Decompile_OutputFileExists_Force_ShouldSuccess

Again, let me know if you'd like help or don't have time. Thanks!
