Ugh.

I'm not sure "<1" will appeal to people who are into round-tripping.

I think my (slightly) favoured option would be to remove the location 
constraints on Features completely.  I know this is pretty horrible, 
but off-sequence locations do seem to be things people use.

I'd definitely vote against special-casing locations at position 0 -- 
that just feels like a slippery slope.  What happens when people want 
to model larger leader-peptides in this way?  If we're going to allow 
off-sequence locations at all we should bite the bullet and allow them 
without restriction.

*sigh*
