I don't recall seeing an acknowledgement for the target tier policy with regards to this target so could you please quote the corresponding requirements verbatim from the tier 3 target tier policy to explain how the target meets those requirements (leaving a new comment here is fine). You can find an example of this in the PR description for #86191. Thank you! 🙂 |
@wesleywiser Thanks. The proposal to add the |
Okay. I rechecked MCP 518 and in fact it doesn't explain verbatim how the target meets requirements of target tier policy. I'll make it clear here. 😃 |

Turns out this was added in the tier 2 section, not the tier 3 section. That's pretty hard to see during review since the diff doesn't show the section header...
I wonder if there's something we can do here, like split the tables across multiple files?
