Being realistic, there are very few applications that are carefully
written these days and account for database specifics. The key
development metric these days is time to market and not quality so
very very few development shops will take time and implement rolling
upgrades for its versions. Though, it might take a while and we can
see it happening for SAP, Oracle Application and those alike. But this
would be tremendous efforts and require the feature working really
well. :) So it won't happen in 11[a..z] and probably even in 12
looking at the quality of latest releases.
The good news is... more DBAs will be required. 8-D

IMHO the point is that presently *no* application is able to take
advantage from that feature. But in the future if you really need to
upgrade an application while it is online, you may take advantage from
editions, edition views and cross-edition triggers to do so.
