Hi,
just a new user to org-mode, I apologize directly for jumping up and raise the 
hand ;)
Other Projects run a little smooth transitions if changes like that are going 
to be performed. 
Maybe it is in general interesting to create a protocol which will do 
something like

1. For the next n releases, both keys are present by default. However, using 
the arrow keys will create a warning message in the minibuffer ala
"The function of the arrow keys are obsolete please use n or p see xyz.org for 
more information"
2. After n releases it might be clear to the majority of all users and they 
either updated there conf-files for an individual solution or got used to the 
new style.
3. Perform the transition and "switch off" the obsolete keys


Just an idea

Greetings
