This is stupid. Almost anywhere in the western world you are going to have high speed connection which will easily deliver 5.5Mb in reasonable time, and modern smartphone do not choke on it. By itself the reduction is not an indication of sustainability if you need to put in more effort to generate it, and it is against what users want if you degrade the user experience to get it.

If it is a matter of reducing bloat than it has very little to do with sustainability and more to do with following good software development practice and obviously reducing the cost of the bandwidth.
