I believe that once was said (on a typo3 core meeting on IRC)  a  
sysext depends on a specific core version.

For example you cannot put css_styled_content on TER because the  
latest version that is compatible with 4.2.0
will properly not work on older versions of TYPO3. Same goes for DBAl  
and other highly TYPO3 version depend extensions.
