Last I checked the Puppeteer and Gutenberg source codes, this event
is not actually consumed by anything. I believe Puppeteer moved to
use the newer
Fetch domain for network interception.
I just missed this comment when updating the whiteboard entry. You are right. There is no usage of
Network.dataReceived in the Gutenberg e2e tests. As such it shouldn't block the alpha release.
During one of our London meetings, we grepped for usage of the Puppeteer "on" method(s) in the e2e tests and found nothing, so based on that there's no explicit reliance on any CDP event in gutenberg tests. There may be more subtle dependencies (perhaps like https://bugzilla.mozilla.org/show_bug.cgi?id=1589784#c1).
More importantly, some Puppeteer functionality depends on CDP events, and those that actually show up during a gutenberg test run are a higher priority than those that don't. That list at https://wiki.mozilla.org/Remote/PuppeteerCDPUsage#In_Wordpress_gutenberg_test_suite
