declarativeNetRequest modifyHeaders action.type

Currently Safari does not support modifyHeaders as an action.type when using the declarativeNetRequest API.

Does the Safari team plan on building out this action.type for the API?

Safari seems to be the only major browser that lacks support for header manipulation, even with the mv2 APIs (ie. webRequestBlocking).

Is this purposefully being omitted? If so, why?

+1, would also like to know if there's any plans to support this or the intent behind the lack of support.
