I do not believe that this the place to deal with versification, but I do think we need to look long and hard again at versification and probably redo the categorization scheme completely. The categories make no sense to anyone but an expert (one who has memorized which versions are in one or other category), and in any case (nearly?) all versions then add a custom.vrs which make them unique. The system is quite confusing and in need of an upgrade.
Most projects in any case are going to copy a complete versification (with further tweaks) scheme from a given version, which is of course not just English or whatever (terrible names, once more), but also the custom.vrs of the copied model version.
