Out of curiosity: why would anybody not use RTTI ? Why shouldn't
compilers without RTTI just considered broken ?

Being able to switch RTTI support off just introduces binary
incompatibilities
and makes some code illegal (you can't cast between classes with a virtual
inheritance relationship without dynamic_cast, etc.)
