CSP in meta header unsupported? Link to discussion?

I cannot find any reference to support or non-support for CSP via meta
http-equiv tags in the current draft
https://dvcs.w3.org/hg/content-security-policy/raw-file/tip/csp-specification.dev.html

Also, a search through my email doesn't reveal any obvious discussion on
taking meta header support out. On the contrary, I found several references
to meta header support from 2011. Is there a discussion I've missed?

If meta header support was dropped, have we considered all the
frontend-only apps being built out there? I have several projects of my own
that doesn't have a server-side and with regular hosting providers you
don't get to simply add response headers to the web server.

I would also argue that adoption is far simpler if you can just add a meta
header in the index.html of your single-page app than start configuring the
web server locally, in the test environment and in production with
potential changes in outgoing filters etc. Even scoping is much simpler
with a meta header in a static file instead of configuring response headers
per context root.

Thoughts?
