Yeah, I see your point.
I do not really why soft-offline strived so much to left the page
untouched unless it was able to content the problem.

Note that if we start now to poison pages even if we could not 
content them (in soft-offline mode), that is a big and visible user
change.

Not saying it is wrong, but something to consider.

Anyway, I would like to put that aside as a follow-up
rework after this one, as this one already changes quite
some things.
