A capability is needed to Test If a DID Exists on the Ledger ...without having to incur the cost of constructing and returning a DID Document.

The DID Resolver Response should contain something like a simple Boolean (True/False) response ...and not a DID Document.

I agree this seems like a good idea. It will probably be an optional feature for DID methods and resolvers.

this is a turning complete problem. Meaning that the only way to be sure a did is NOT there is to run the full chain. It would take less time only if there were a did that as active sometime in the recent past. Which is also a "freshness" measure. Thus the return may as well return the date of last use.
