This is not a problem at all, because as soon as new extensions gets
added, the wizard simply has to check if this "wizardDone" setting is
"1" or has a timestamp of whatever will be the choice of the new release
to differenciate the situation. "==1" means it was done in 4.5.

This would be the correct approach, but we don't need this complexity
while there is no need for it. As soon as we have the first "use case"
for this, we can have a solution. Is there already demand for it?
