This Intent is missing several important fields for a deprecation and removal, such as: Web developer signals, WebView application risks, web platform test support (it's best to add negative tests which only pass after the removal), Debuggability (how hard will it be for developers to debug failures due to this feature missing?), Finch feature name / non-Finch justification, and Estimated milestones.
Some of these are probably not too serious given the low volume of usage, e.g. I suspect no special debuggability support is required. But it'd be helpful to include them all. Additionally, the Enterprise, Debuggability, and Testing gates have not been requested yet. Would you be able to re-generate the Intent email after filling in those fields and requesting those gates? (You can send the updated version to this thread; no need for a new one.)
