it would be nice to come up with some level of automated conversion.  no 
matter how much we say "read the docs", there will always be people who do

because how much we've done to auto-migrate settings.

you can add an ewarn now while continuing to parse the code.  but the same 
issue as above ... there are many systems which are headless where these will 
not generally be seen.
