Each PHP version is supported for 4 years by the PHP project [1], thus

forced to upgrade to a supported PHP version.
That point is moot for a lot of software where the developers are not
necessarily in control of which PHP version is used (e.g. WordPress).
In practice this kind of software already needs to check the PHP version
and newer PHP versions need to be allow-listed, since newer PHP versions
might introduce breaking changes that do not go through the deprecation
process (some of them might not even be considered a breaking change,
e.g. the introduction of a new class or function). This kind of breaking
change would provide even less of a “heads up” compared to a
Deprecation. One of those that affected myself was
