The latest proposal does not require support for wallet-initiated flows as a MUST have requirement (only issuer-initiated flows).
In the DIIP community we have had several use cases that demonstrated/used both flows. Als for the Sustainable Cities interop track we would like to demonstrate how credentials issuance flows can be either started from an issuer portal or from the wallet (personal wallet or organizational wallet).
So I suggest to have both flows as MUST have requirement for DIIP V4.
