For some applications that makes sense.

  Look: you have an old database without new data types and an old
application that works with it. The only way to put this old
application into troubles is to _change_ type of an old field because
with newly added tables and fields the application will be fine as it
has no idea about them.
Now tell me: does changing of old fields into new datatypes really make sense?

Have you never used tools or libraries that didn't support newer features of Firebird? These compatibility options are extremely necessary, especially with all kinds of tools that are still being used but aren't being maintained anymore.
