I am strongly of the opinion that this is a misfeature in python and php. I suspect that most python and php programmers would be surprised to discover they behave that way. If there are two possible matches with different lengths, having the non-greedy RE give the longer of the two, the same as the greedy RE does, violates the principle of least surprise. As regards "macOS is generally slow on adopting conformance to newer standard", that is irrelevant. This new addition in POSIX is intended to be a standardisation of long-standing existing practice. We would need a very good reason to specify behaviour that is different than that existing practice, thus breaking not just the existing implementations[*] but also applications that rely on the existing behaviour. It doesn't matter that they were not "portable applications" when they were written if a forced change to existing implementations is what causes them to break. [*] Yes, "implementations" plural. Known to be at least macOS and DragonFly BSD.
