Currier A/B split is not what we thought it was!

Yes, there are some implications for potential generators (generators are not meant to decipher, but I get your point): 
1) Discrete folio-level switching between two states with well-separated rates
2) Compatibility with a template system with fixed and switchable classes, where fixed templates are invariant to the switch and switchable templates respond strongly with no reversals.
3) A gradient, orthogonal to the bimodal switch
4) At least three functional regimes among character pairs (categorical, intermediate, free-variation)

So, from your answer I assume there are some implications for the generators but not really for direct deciphering attempts?

Exactly! As far as I'm concerned, I'm not working on cracking/deciphering the VMS, but on finding hints on its underlying structure through machine learning, which I think is more likely to bear fruits at the moment.
