Are there use cases where the REQUEST is required or is this 'just' a 
backwards compatibility issue?

How do you encourage people to adjust their import/export steps? People 
will write new steps that depend on REQUEST if there are no deprecation 
warnings.

I'm not sure if the import/export steps used by CMF are clean or if 
nobody recognized the issue because nobody runs import/export steps from 
a portal_setup tool that was looked up as utility. Maybe the issue just 
shows up in combination with portal_quickinstall?

I don't like to remove CMF's portal_setup registration *if* CMF itself 
is not affected by this issue.
