Its kind of funny but thats how user agents have been for a while. It's historically just been browsers pretending to be one another.

Yeah and that's why it's one of the basics of the basics you learn as a software developer that you shouldn't sniff the useragent, because it's unreliable and causes issues. Yet all big webpages (especially those pretending to be a software) do it, causing issues. Even just trimming the useragent string (xorigin.trimming.policy) makes "advanced services" like a webshop unusable.

Just don't do useragent sniffing, do feature detection instead.
