Not quite true. It is, in theory, also supported for configuration, 
*but* if you render a form field in fluid it will generate a property 
mapping configuration for that property using a concrete index:

<f:textfield property="families.0.age.birthDate" />

Will create a property configuration for families.0 to allow creating a 
family object and to allow the properties of the family object.

Now when you use

->forProperty('families.*')

in your controller, this configuration is added, but when fetching the 
configuration for 'families.0' again, the auto-generated configuration 
from Fluid will take precedence and everything set for 'families.*' is 
ignored[1].

Recursively setting TypeConverterOptions *never* works for the reasons 
described above.

This is indeed the only solution currently if you use Fluid for templating.

Kind regards,
