OK, I'm mostly convinced. (As I said that doesn't take much in this
case :)

I'd still like to see some adoption first. I suppose
 debtags search 'implemented-in::perl && interface::daemon'
would be a good start in finding likely candidates.

I suspect there aren't many: AFAICS the affected daemons are only those
ones that don't load all their modules at startup, but rather require()
them only when needed.

Given the silence so far, if more affected packages are found I don't
think this discussion should block filing wishlist bugs. 

OTOH, if spamassassin is the only package affected, do we really need a
policy change at all? I'm not really opposed to it, and it could benefit
future packages getting things right from the start, but it is a bit on
the heavy side IMO...
