As suggested by @cedric-anne in sabre-io/dav#1556 (comment)
I manually added an
= nulllocally to a function parameter, and ran cs-fixer. It correctly reported the problem and added the fix - putting the?in front of the type declaration. So cs-fixer running on PHP 7.4 will find and fix this issue that causes deprecation warnings on PHP 8.4.
