Since we're touching this already, wouldn't it be slightly better to 
have all of the above in lowercase instead of uppercase? They look like 
#defined-ed constants otherwise.

Also, should we consider converting DISASSEMBLY_SOURCE_DEPRECATED or 
should we let it go? It was introduced in 2015.

Otherwise looks good to me.
