TL;DR

• h2 Push is not production-ready yet, but excellent for experimentation!
• TCP slow start, resource priorities, buffering and caching conspire on a low level to make h2 push difficult to fine-tune
• Best practices for when to use push vs Resource Hints are unclear
• Automated tooling is probably going to be the preferred way to use push, especially on a CDN level
