Why not implement the transformation in spring's TypeConverterSupport, but delegate it to TypeConverterDelegate?

In

spring, why not implement the transformation yourself in TypeConverterSupport, but delegate it to TypeConverterDelegate?

Jul.12,2022

look at the versions of these two classes from the reason why you use Delegate (extending the method of a class).
seems to be because TypeConverterDelegate first existed in 2.0, and
TypeConverterSupport in 3.2. I want to extend TypeConverterDelegate (but it doesn't seem to extend anything.)
