Subject Re: Signed RSL from Apache

Talking about security, I think there is nothing being done to prevent
man-in-the-middle for JS libraries hosted by Google for example, so it does
not seem to be an issue even if JS is plain text and easier to manipulate
(I did not hear about such an attack). Is the RSL issue we are talking
about a real issue?
