* yes for all options for new variables
* yes for public for existing variables
* no for private and protected for existing variables as this could 
break stuff if you make them private even if they always were meant to 
be private (... we never know what people do ...)

anyway we could have getters/setters for existing - meant to be private 
- variables and say that in 4.4 or 4.5 we finally make them private...

then they simply need to set the requirement for TYPO3 4.2+ in 
ext_emconf.php
