We have secure boot on s390 and support for POWER is in progress (expected in
15 SP5). Maybe the kernel makes this look like EFI to userspace but the
expectation is that we will have a different tool for POWER eventually.

To the contrary - code that exits at random is difficult to follow, and is the
very cause of bug 1189841 - if your code does not run because of IFS set at the
start of because of a test exiting at the start the result is the same - the
code does not run.
