The following is the most recent and, as it transpired, potentially final update on the status of the BabelStone Han variation selector sequences:
> “It is intended to register a BabelStone Collection in the IVD at a future date when the sequences listed here are stable. […] NB I plan to reassign most of the IVSes marked with an asterisk so they have a unique IVS sequence. When the CAAPH collection is accepted for registration in the IVD I will also need to reassign many of the BabelStone Han IVS sequences which conflict with the collection.”

Now, I'd always wondered when “when the sequences listed here are stable” would be—but I was not expecting that it would be as soon as this year that BabelStone's untimely passing, not long before the CAAPH collection was registered, would sadly settle that question.
Consequently, I do wonder about the future status of these variation selector sequences, given that the current versions of the BabelStone fonts are presumably either final or, at minimum, would effectively serve as a memorial watershed. In particular, those of the sequences implemented by the current version of the font which do not conflict with existing registered IVSes.
