Ok, seems very intriguing. I started reworking webapp-optimize to behave similarly for locales and js (I can even imagine using similar grouping strategy for locale resources one day).

I didn't get LazyLoader updates, so for now it's getting the startup path code, but erroring on LazyLoaded stuff, but first results:

music.gaiamobile.org   base: mean  2: mean  2: delta  2: p-value
---------------------  ----------  -------  --------  ----------
navigationLoaded              751     732       -19        0.10
navigationInteractive         780     760       -20        0.08
visuallyLoaded               1241    1163       -78      * 0.00
contentInteractive           1241    1163       -78      * 0.00
fullyLoaded                  1546    1358      -188      * 0.00
uss                        17.701  14.451    -3.251      * 0.00
rss                        37.380  33.836    -3.544      * 0.00
pss                        21.991  18.788    -3.203      * 0.00

and that's even *before* I was able to get any optimizations in. 


I don't trust the mem numbers because I believe that once we load the lazyloaded pieces it will be a smaller win, but there still should be a good mem win because I'm able to reduce the size of the .zip package from 3.2mb to 2.1mb.
