File formats are one of those things where a little time early can save a lot of work later. If there were a strong reason to use "1" and "2" here then I'd be okay with living with it --- I'm a pragmatic person. But in general, using the magic numbers instead of a sequential value is really helpful both in making the file formats more self-explanatory and in making it possible to experiment with multiple new hash_algos at the same time. The main argument I'm hearing for using "1" and "2" is "because some other formats got that wrong". That reason is the opposite of compelling to me: it makes me suspect that as a project we should more eagerly break the old bad habits and form new ones. I guess this qualifies as a very strong opinion. Thanks, Jonathan
