  If the change should also go to maven-3.9.x, request a backport in the PR.
  maven-3.9.x should receive only serious bug fixes, as it is approaching EOL.

Backports are typically handled by maintainers; 
however, after agreement you may open a separate backport PR to the target maintenance branch.

In these examples we've prearranged which root certificates to trust. But for regular HTTPS on the
Internet this set of trusted root certificates is usually provided by default by the host platform.
Such a set typically includes many root certificates from well-known certificate authorities like
Entrust and Verisign.
