Yes, it's a terrifically useful format overall. My question was about that curious first line, however -- whether I can safely delete word 5 to -1 of line 1 (I mistakenly said 'word 4 to -1' in my original post) and get a pure list of handlers with their types and lineoffsets. I don't know why the LC team didn't put the long id of the object in line 1 and start the handler list at line 2, and I wanted to make sure that this oddity persists in later versions of the engine.
