import_steps.xml and export_steps.xml were deprecated a while ago since 
they caused very confusing behaviour: they were loaded when a profile 
was activated, but they were loaded into a global registry of known 
steps. The result was that the list of steps could randomly change 
depending on which profiles you had looked at in the ZMI. In order to 
simplify things those two files were replaced with zcml directives.

I am wondering if the CMFCore import/export steps are registered for 
Interface instead of ISiteRoot? You should only see steps that are 
registered for the current context, and since a PAS user folder is not 
an ISiteRoot the CMF import and export steps should not show up or be run.
