Jan Lehnardt commented on COUCHDB-1654:
---------------------------------------

@Benoit, I respectfully disagree. With the principle of least surprise, 1.3.0 
should *not* rebuild view files after an upgrade just because we fucked up 
signature generation.

I propose we make this part of the etap test suite and ensure that this is 
fixed now and in the future. Same with db signatures.

If we need to change things in the future for more severe reasons, I’d suggest 
we treat this as a BC break and accompany such a change with a major version 
number increase and copious release notes..
