Client Hints as a replacemtn for UserAgents?

[thohan]

Has there been any discussion or research into using the newer technology of Client Hints to replace UserAgents in the webparsers?
While I realize that this is a little early to be worrying about this, especially since the use of UserAgents has not been depreciated and not all browsers support them, the use of Client Hints does seem likely to become ubiquitous.
Would there be any advantage to using them or security problems? I was recently reminded of the weather.com problem we had awhile back solved by the use of the AgentString (https://forum.rainmeter.net/viewtopic.php?t=35770&start=650#p226769) and this prodded me to ask about this.

I'd be curious about that too, but more importantly, whether or not these Client Hints can be safely and effectively spoofed in order to allow WebParser to parse the same data as if the request was sent by a browser, for whatever sites that don't particularly like the default WebParser user agent.
