Do we explain somewhere in the UI that "Fleet Desktop" is in beta? (If so, shouldn't it be unchecked by default?)

@lucasmrod there isn't any explanation in the UI. However, the release blog post and release notes will be loud about "Beta support for Fleet Desktop" and link to this issue that includes the work to bring Fleet Desktop out of beta: #5684

What do you think? Do you have any concerns with this approach?

shouldn't it be unchecked by default?

Yes, the option is unchecked by default. I checked the checkbox before taking the screenshot that's in this issue's description.

Sounds good. (Though there will be some users like me that won't read the docs/release-notes and will try it out :)

Awesome.

Looks good. @noahtalerman were there any integration tests previously written that should also be enabled?
