Comment (by i139):

 Adaptive bitrate Vs Obscurity.
 the major beneficiary with this will be live streaming, like twitch or
 conferences that doesn't run without MSE and some sites that use dynamic
 javascript like twitter.

 somehow, maybe the user should have control above this choice (without use
 about:config) maybe put this in the security slider or a checkbox option
 you have an observation about a possible exploit?
 those information have to be put in the manual.
