Not all versions of the past will work as value, mainly to be used with
values "0" or "CURRENT". If any new deprecations are done without
having code starting to use older deprecated API, in the future any
versions >= 5.71.0 should work also reliably.
Currently a build with EXCLUDE_DEPRECATED_BEFORE_AND_AT=CURRENT does
not yet work, some API deprecated is still used internally by
code behind non-deprecated API. Building with CURRENT will show by the
failed build which those are.
