When it comes to Galaxy "Note".. The only thing that comes in mind is the best and ultimate what Samsung can offer in its smartphone division.
The word "Note" was enough to signify the ultimate of Galaxy smartphones.
Adding the word "pro" degrades the meaning and superiority held by the word "Note" in Galaxy series so far.
Secondly it looks like Samsung is following naming trends of Chinese smartphones like One Plus 7 pro and may other pros out there.
PS: If there are two or more variants in the Galaxy Note 10 family. Let the most superior one be "The Galaxy Note 10" and lighter variant can be named "Galaxy Note 10e" or "Note 10 mini" etc.
