Hey there @garbled1, @epenet, mind taking a look at this pull request as it has been labeled with an integration (onewire) you are listed as a code owner for? Thanks!

Could we add a note to say: "install owserver"?
And what happens for migration to custom component if we keep the domain for owserver implementation?
I'm not sure if there are other components on ADR19 that have this dual access.

Feel free to suggest an edit.

It would need a different domain (which is recommended anyways).

I'm not sure if there are other components on ADR19 that have this dual access.

Adjusted, thanks! Did a bunch of these, so copy-pasted a lot 😄

I think the warning in async_setup_entry should be removed.
I would maybe adjust the warning in onewirehub to encourage users to migrate but that is maybe optional.
