The spec currently makes the identifier just the scheme data, which seems much more complex than it needs to be.  revokeObjectURL should simply be "Remove the entry from the Blob URL Store for URL."  If we want to allow revoking URLs that have a fragment attached it'd still need to strip it off; Firefox does this, but Chrome doesn’t.


There’s no good reason not to do this. The scheme data identifier is a hold-over from the “only UUID” model that Fx has right now (the original intent was to have a table full of UUIDs and blob references). I’m happy to change to this model.

OK, this is a good nit too.
