The rule is actually pretty simple: we follow MySQL's official  
support cycle.  When MySQL drops support (and security updates!) for  
a specific MySQL version, we drop that version as well.  When your  
hosting company is not willing to upgrade, just tell them they are  
running an insecure MySQL version (unless they have a support  
contract with MySQL).  I'd say this makes for a simple rule of thumb,  
that requires very little discussion.  Hence the prompt decision.  :)
