Refreshing was always a hack and never something I would call a feature.
It was always a hack for *development* purposes but not for production.

You might blame Plone for shipping for three tons of frameworks?

I understand and fully agree with you but things are as they are. Even

Refresh only works in debug-mode. You want to tell us that you are running 
a production site in debug-mode?

Dieter Maurer wrote a RefreshTool product lately (not sure if this would 
solve your problem and not sure if he released it).

I doubt that the Refresh situation will change in the near future.
