Just adding here that POSIX.1-2024 removed the -a and -o operators [1]: Austin Group Defect 1330 is applied, removing the obsolescent (and optional) -a and -o binary primaries, and '(' and ')' operators. So I don't think we should spend much time worrying about it. That is my excuse at least. Will leave this bug report open though.
