This doesn't really add anything.
I'd like to know the particular bug which prevents symfony working with 5.3.16...

@bendavies see https://bugs.php.net/bug.php?id=62874 But how does it help?

---------------------------------------------------------------------------

@fabpot there are already three recommendations that point to the actual php.
https://github.com/symfony/symfony-standard/blob/master/app/SymfonyRequirements.php#L516
https://github.com/symfony/symfony-standard/blob/master/app/SymfonyRequirements.php#L522
https://github.com/symfony/symfony-standard/blob/master/app/SymfonyRequirements.php#L528

So number 1, nice for consistency, and number 2, as an inquisitive person, i just like to know _why_.

I think @bendavies is right, it improves consistency with other messages so I added the reference.
