More webpack splitting
What does this MR do?
Allowing it up to 5 initial requests (default is 3) means it can do significantly more splitting, most pages will then have 2 fully cached chunks so it won't be loading 5 in parallel on most page loads anyway.
How confident are you it won't break things if deployed?
All should be well :)
