[FrameworkBundle] Add autowiring alias for PSR-14 #32295
I think requiring Psr\EventDispatcher would be developer friendlier. Currently developing against
This was done because of the min php version requirement in psr/event-dispatcher, I see. I would suggest to create a minor release of https://packagist.org/packages/symfony/event-dispatcher-contracts that raises php requirement to 7.2 as well and requires psr/event-dispatcher. So people on PHP 7.1 would get the current version and php 7.2 and above the better DX.
