Looks like you got a response on sword-devel.

While I understand that support for versification as a whole might be tricky, I'm not sure I agree with the fact that patching from one to another is tricky as well.

There are bound to be changes (new/custom versifications, bug fixes, oversights, etc.) We can easily provide a tool that inserts splits and rewrites all the mappings safely for that.

I'll wait and see what comes of my post, but on the other hand, STEP needs this rather quickly (doing text comparisons, parallel texts and interlinears). I have the mappings for the Masoretic Text which would solve most of STEP's interlinear issues when using 1 or more ancient texts. And there's nothing to say that we don't put in the mappings one by one, especially if we provide a tool that can do that.

It then queries the master mapping, which returns 1 or more entries (an entry being a whole verse, or set of split verses). Then goes to reverse mappings for the target versification and does the same. For incomplete verses on one side or the other, we round up the closest verse.
