As explained in https://twitter.com/nicolasgrekas/status/1263023258938548225:

Using `"^7.x"` is our composer.json has been a mistake. We should always use `">=7.x"`! 3 reasons:
1. it's either planned obsolescence xor a strong promise to maintain in the long run. None is sustainable.
2. if you actually end up maintaining in the long run (not by promise but by fact), your latest versions will work with PHP 8 by definition.
3. meanwhile, `"^7.x"` prevented all your ecosystem from experimenting with PHP 8, which means they increased the workload on *you* the core maintainer.

Conclusion: always use `">="` for the `"php"` requirement. Hope for the best (it mostly happens) and enable your community to experiment with the next major asap without adding useless impediments.
