Indeed I believe you have to.

I may have missed it, but one thing I haven't seen in this thread is
feedback from Mozilla. I point this out because a few years ago they
experimented rather thoroughly with something known then as "Limi
Packages". They tried a bunch of approaches and the outcome was that
they only saw moderate improvements at the best of times, while also
seeing it made it really easy for developers to rely on this as a
footgun, leading to degraded performance. In my last discussion with
them (after a thread on WebApps I was a party to essentially reinvented
the same solution) they indicated that they saw no advantage that
wouldn't be addressed better by HTTP2.

(And other points in the thread.)

The place to get that information from would likely be:
http://commoncrawl.org/
But it's more than a five minute job.
