Comment (by Clorith):

 Really, what we need is a "new" approach altogether, see this ticket
 spurred by Gutenberg and it's increased demand for JS:
 https://github.com/WordPress/gutenberg/issues/4150

 Basically users are already experiencing issues due to the scripts loader
 on shared hosts where the file fails to load, and thus leads to lost
 functionality on sites. The only fix in those cases is to disable
 concatenation which requires editing `wp-config.php`, and we don't want
 users to need to do this.

 We could therefore focus this ticket on improving the various overheads
 (memory, processing time and the likes) and hit two birds with one stone
 (hopefully).

 Some scenarios that cause the concatenation to fail in one way or another:
 - Required too much memory
 - Execution took too long
 - Query string too long, some libraries not included
