I am not sure how to get to the patch, but I suspect you might be
misreading "up to X", which is different from "before X".  Once cURL
mailing list confirms my suspicion, we would need to come back and
update this patch again.

Ah, I found it at https://curl.se/mail/lib-2021-07/0058.html

Nobody seems to have responded yet, but I do think you are
misreading what "X was known under a different name Y up to 7.16.4"
means.  These places do not say "before 7.16.4", which would have
implied that as of 7.16.4 you would be able to use X (not Y).

But because "up to" is "less than or equal to but not more than"
(e.g https://dictionary.cambridge.org/us/dictionary/english/up-to),
what applies to 7.16.3 also applies to 7.16.4, but not to 7.17.0.
IOW, the feature X was known as Y when 7.16.4 was current, so our
use of X would not have worked with that exact version.  We would
have needed to wait until the next version (7.17.0).
