+1.

I have a concern about this orthodoxy of always putting service worker
apps under TLS.  Since the STRINT workshop, and also in light of the
coming move to http/2, Iıve been talking to a lot of web developers about
moving to https.  Iıve heard a lot of concerns with this, even from large,
established web sites.  Developersı concerns generally fall into the
following categories:

1. TLS itself is a pain to administer - the logistics of the certificates,
installing them, making sure they remain valid, ensuring they cover all
the needed domains, keeping up to date with best practice, etc...
2. https sites require beefier hardware to serve
3. https sites are more difficult to load balance
4. serving over https makes it much more difficult to use third party
content (scripts, images, videos, ad networks, whatever) in your webapp

A head of advertising for a major UK web site told me ³moving to https
means we will lose money.²

Iım not saying these concerns arenıt addressable in the long term, but I
wonder, specifically looking at service worker, and considering that
adopting service worker will already mean a big learning curve for web
developers, whether enforcing TLS-only for this burgeoning technology is
the right approach.

In this light, I think Yoavıs proposal deserves some additional
consideration.

Alex, Jake - would be good to hear your opinions on this.
