Looking through the request, while I note that it's a small change there
is also quite a few fields not filled in. For instance, no explicit
requests for official Mozilla or WebKit standards positions, no TAG
review, no web developer position, and more.
Could we get some motivation for skipping those fields, or if they
should not be skipped, well, updated info?

Open questions about a feature may be a source of future web
compat or interop issues. Please list open issues (e.g. links
to known github issues in the project for the feature
specification) whose resolution may introduce web
compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
