Well correct me if I'm wrong, but when you update a plugin 
automatically it deactivates, upgrades, then reactivates?


I make changes to the database tables created by the plugin on 
occasion (plus occassional settings changes), and I have always used 
the feature of the activation hook being run. I do my version check 
within there.

I even coded something to highlight that the version number hadn't 
been updated thus prodding them to deactivate/reactivate.

If this 'feature' was to be removed, then it would affect many many 
plugin authors(IMO) and time would be needed for them to adjust to things.
