What I'm reading into it is:
  * A prominent (the most prominent?) microformat-to-RDF converter  
ignores profile for microformats and rel=transform by default, so  
authors can have their stuff consumed even without the profile.
  * There had to be a reason for a presumably well-informed developer  
to do it this way instead of just observing profile by default and not  
sacrificing UI real estate for configuring the behavior.

Given that you are doing what you are doing (regardless of *why* you  
are doing it), what incentive is there for authors to use profile?  
What do they gain if they use it? What incentive is there for the  
users of your software to change the default settings?

Have you analyzed your logs to see if your users do change the  
defaults often?

How does this follow?
