I wonder why does it work for Scala 2, but it doesn't for Scala 3 port.

At the same time we could consider renaming the inspection the ...Exception is indeed a misleading name for a class which is not an Exception or Throwable.

Maybe it works with @nowarn in Scala 3?

@mccartney, should we wait for you to open this PR or release a new version with Scala 2.12.21 before?

Nah. Don't wait for this PR. This is not done yet. And I fail to know when I will be able to continue the work. So go ahead!
