IIUC, UIStatusFromModelStatus will be a really common name.
it should be renamed ReadingListUIStatusFromModelStatus or moved to a
reading_list namespace.

Done.

I think the real problem (that confuses me most) is not the existence of
UIStatusFromModelStatus but the existence of ReadingListSuggestionDistilledState
which was discussed in the previous CL.
So this is out of the scope of this CL and this is fine here.

Acknowledged.
