I don't want to take this thread too far off topic, but the "we'll
have changing breakpoints at some point" problem is a major reason why
http://www.w3.org/community/respimg/2012/05/13/an-alternative-proposition-to-and-srcset-with-wider-scope/
was thought of. It has it's own drawbacks, but it does address the
problem of breakpoint management and centralisation of breakpoints
throughout the technology stack of HTML/CSS/JS.
