After reading the thread,

Seems like it should be called “prefix delegation” instead of “share”.    That is, as I understand it, the purpose of the proposal.

I would prefer it to be a standard as the intent is to use it with 3GPP style networks.

I like using RA for this as it appears to be a better fit for 3GPP style networks than DHCPv6 PD.
