The project isn't automatically fixing compiler warnings or library deprecation
warnings in back-branches. I guess one could make the argument for this case
given how widespread OpenSSL 3.0, but it comes with a significant testing
effort to ensure that all back-branches behave correctly with all version of
OpenSSL so it's not for free (it should be, but with OpenSSL I would personally
not trust that). Also, PG12 and below had 0.9.8 as minimum version.
