That's got nothing to do with this. It's still the same "workflow tool" 
import step, it's just operating on a different context (your own 
workflows.xml in this case).

It's the same for all steps. You can modify (with an extension profile) 
an FTI in portal types via types.xml + types/typename.xml. If you 
specify a subset of properties, those are updated, but others are kept 
the same. Same with propertiestool.xml: you don't wipe the 
portal_properties tool by using your own propertiestool.xml, unless 
you're running a base profile (which most people aren't).

Yes, but not for the reasons you mention. :)
