At some point, projects will never fix a bug for a specific version. For example, if a project is up to version 2.5.3 and 1.2.3 was released four years ago, it's very likely that any bugs filed against 1.2.3 would just be closed as wontfix. It should be possible to just prevent tickets for that version from being posted in the first place.
This can either be done by limiting which versions are shown in the ticket creation page or it can be done by showing an error message if that version is chosen. Limiting the versions shown avoids the user needlessly entering the bug information, but showing the error message when the version is selected leads to better discovery that the version is no longer supported.
