In a few hours, I'm launching a very large website that relies heavily on LoadCSS(). Page load times have been excellent in the pre-public phase, even though our critical styles contain a mountain of Autoprefixer-generated flexbox prefixes.

My understanding is that all of this will become an antipattern once we can support http/2. For today, however, it provides a very real performance boost.

My understanding is that concatenation will be become an anti-pattern with http/2, but not `<script async..>`, `<script defer..>`, or loadCSS.
