Packages in universe don't migrate to main in a released version of Ubuntu. Please read again comment #11, one can be fairly confident that critical security issues will be fixed in such an important package, even after the official support period has ended. If you don't trust the Ubuntu community on this matter, you should upgrade to the next LTS (focal).
