to be honest I think yes.
As what I have understood. It is very useful your note about symbian because I was just asking to myself how it was possible to have the same information for symbian applications. Now I am working on a Meego development so I will check in next hours if the application version really propagate to the in-program information.
The fact is that in Harmattan (that is a linux os) you are obliged to set the versioning in a correct way, not only. As I have experienced publishing with Ovi Store my Harmattan Application, the version number can only grow and never change with numbers less than the last you have created. Ovi store take this information from the application and the installer too: in the application info when it is installed on the device one of the information you see is just the release.version.subversion numbers.
Instead for symbian devices Ovi does not mention this aspect regarding the publishing of the applications. I was confused about the symbian case so now I check Harmattan and tell you asap. For symbian, I keep correct what you tell but I should read again the publishing specifications of Ovi Store. It is possible that before publishing Ovi requires a valid versioning system - with the method that you have mentioned - also for the symbian applications.
Without any settings, the symbian installed applications reports always the version 1.0.0
