Hi Daniel,
Indeed the term is confusing as IIUC it's not to announce that an origin
trial is ready, but it's early in the process:
https://www.chromium.org/blink/launching-features#TOC-Step-3:-Feature-Complete-behind-a-feature-flag:-iteration-on-design
According to the documentation, these "Ready for Trial" mails are to
announce that your prototype implementation is completed (behind a
runtime flag) and people can start to play for it.
They have nothing to do with Origin Trials if I'm not wrong.
I'm not sure if these kind of mails are really important or not, maybe
in some big features they're useful, but we should avoid "trial" word on
them to avoid this kind of misunderstanding.
Maybe something like "Ready for testing" (or "Ready for playing")
explain better the purpose.
Or maybe I'm the one that is totally confused, but in this case we have
to update the documentation in
https://www.chromium.org/blink/launching-features.
Cheers,
Rego
