I see that iter links (and probably other) don't support Detach(); should we add a test for one of these cases? also, should we explicitly return ErrNotSupported?

sorry for the delayed response 🙏

With 2520bb8 I have added such a test.

[..] should we explicitly return ErrNotSupported?

With c92c648 I have added an error wrapper. Hope this is fine for you.

lgtm! there are some failing CI jobs, not sure they are related

They don't seem to be related:

=== FAIL: asm  (0.00s)
panic: test timed out after 10m0s
	running tests:
		TestGetSetJumpOp (10m0s)

This is also reported in #1734
