[griesemer]

The FAQ need to be updated with a preamble/disclaimer as it was not written with generics in mind.

It needs more of an update than a preamble. The FAQ should stay current.

https://go.dev/doc/faq#generics should be updated.

Change https://golang.org/cl/374215 mentions this issue: _content/doc/faq: add a couple of generics FAQs

[ianlancetaylor]

There is a CL for this that is waiting for review (https://go.dev/cl/374215). The CL won't be committed until the release.

@ianlancetaylor Since the CL resolving this issue is planned to be submitted right after 1.18 is released, is it okay to move this issue to 1.19 milestone, keep release-blocker label, and add early-in-cycle, so that we can revisit this right after 1.18 is released? That way, the list of open 1.18 release blockers will be more actionable.

[ianlancetaylor]

Sure, I will make those changes.
