They should also enforce a policy for “advanced install” where the store can choose to position the scripts and assets in the code themselves.
I have never seen an app doing this, but they all should. Either go for vanilla - apps adding their assets in the script header themselves, or advanced (Warning! Might break functionality) where you get the src for all required assets so you can combine, minify, defer and so on for apps that either doesn’t need to be loaded in the script header for all pages, or doesn’t need to be loaded in the critical render path for objects above the fold.
