Good question, and of course the difference between 445kb & 345kb may not be noticeable, but it would be if you compared it against 1/2/10mb etc.

The competitive angle is really delivering a fast/snappy/responsive experience on mobile or desktop. That in itself isn't going to save you, but it is an advantage if part of the sell is a high quality experience.

Re:interesting, for instance I just started experimenting with inlining all css/js into index.html (so far the js part is problematic), minifying classnames, and I'm curious if it'd be possible to even minify js module names etc.
