Scrapy currently does not support HTTP/2 Cleartext (h2c) since none
of the major browsers support HTTP/2 unencrypted (refer `http2 faq`_).
Also, Scrapy does not currently support specifying a maximum `frame size`_
larger than the default value, 16384. Connections to servers that send a
larger frame will fail.
.. warning:: HTTP/2 support in Scrapy is experimental, and not yet recommended
for production environments. Future Scrapy versions may introduce
related changes without a deprecation period or warning.
