I already do, it's really not that bad to set up, and the overhead isn't that massive either (at the server end, I don't mean HTTPS vs DNS).
TBH the main reason I set it up, though, was originally so I'd have explicitly configured a service I trust rather than letting a default kick in.
With pi-hole behind it, and Intra on my phone, it means that my phone can never resolve the manufacturer's Telemetry domain, even when I'm out and about, so doesn't send them god knows what either. It tries to resolve that name rather a lot.
