Storing the entry offsets in the blob, as happens with other generated blobs, simplifies the current save/restore API and implementation. It also makes it easier to define and implement an API extension supporting save and restore of multi-stub (StubGen) blobs.

Ah, sorry, the merge appears to have caused some issues in debug builds. Will let you know when this is ready again.
