Has there been any consideration for UA settings being able to make the CSP more restrictive? Like using the presence of a DNT header or an opt-in cookie? Something like 

script-src adco.fr[dnt:0] scriptlib.com;

adco.fr only gets allowed if DNT:0 is present.

Or for an opt-in cookie:

script-src adco.fr[cookie:consent=yes] scriptlib.com;
