Status size missing from BitstringStatusList

[timothee-haudebourg]

Hi, since the Draft 16 April 2024, the status_size property has been moved from BistringStatusList to BistringStatusListEntry. I understand it is sometimes necessary to know the status size from the entry without having to fetch the entire list, but removing it entirely from BitstringStatusList introduces some major issues in my opinion:

• It is now impossible to decode a status list without possessing a status list entry.
• The status size parameter must be passed around in many places of the implementation, making it error prone.
• This differs from IETF Token Status Lists, making it hard to implement a common API.

There is a related comment here for why the spec is in the state that it is in right now: #175 (comment)

4.5. The BitstringStatusList.statusMessages and statusSize properties are still being referenced (issue vc-bitstring-status-list#175)

See github issue vc-bitstring-status-list#175.

Manu Sporny: There is maybe only one implementer for this feature at this point.

See github issue vc-bitstring-status-list#176.

Manu Sporny: Dont think it is currently marked as at risk.
… Actually it is already marked at risk.
… So we are waiting for implementations.

Brent Zundel: My understanding is mesur implements these features.

Manu Sporny: Great. I think Spruce may also be using it, so leaving it in awaiting implementations.
