No longer an issue with current Rakudo​:

  ➜ my @​a = -1, 2, -3; say [+] (.abs + .abs for @​a)
  12

Not sure if a test is needed for this.

I'm not really sure, either. But since we have a bunch of tests for cases where we expect a warning, I went ahead and added a test for the absence of a warning to S32-exceptions/misc.t with commit
Raku/roast@1804479bb2.

I'm closing this ticket as 'resolved'.
