+1 I for one have been burnt more than once spending significant time
on a spec only to find our collective understanding changes after actual
code exists.

For things related to interfaces a spec can be helpful, but I think it's
often faster to raise a blueprint with relatively few details and work on a
prototype that clarifies the direction, particularly if such code patches
can be generated fairly quickly.

I agree - I think a common mistake is to get bogged down in implementation
detail when writing (and reviewing) a spec, so I definitely favor a
clearly expressed summary of the problem, an overview of the proposed
direction (including any major interface changes), and clarification of any
user/dev visible impact.  None of this requires much focus at all on the
details of the implementation IMO.

Thanks for raising this Emilien, hopefully this will help us move a little
faster in future!
