Ability to mark a comment as optional

[starkej2]

When reviewing a pull request, I often find myself leaving comments that are optional or nice-to-haves. This type of comment is usually best left to the author's discretion about whether to apply the suggested changes before merging the PR.

GitHub doesn't currently provide any functionality to differentiate between an optional vs required code review comment, so as a workaround my team typically includes prefixes/emoji such as Optional:, Nitpick:, 💡, etc to provide this additional context.

It would be really helpful if GitHub pull requests provided a mechanism like an Optional checkbox or Comment Type dropdown to allow the reviewer to specify whether each individual comment is a required change request or an optional non-blocking request/comment.

Hey 🙂
This makes a lot of sense, especially for larger PRs where not every note is a blocker. An “optional” or “nit” label could reduce unnecessary tension in reviews.

One question though: would this work best as a per-comment flag or a per-review mode? Some teams might want optional comments by default, while others only occasionally. Native support could standardize what today is just team convention.
