I don't think, that we need to sync Extbase with TCA, at least not 
automatically.
In a lot of cases you want _different_ validation rules in the TCE. E.G. 
you might want to allow "Extbase" as blog title in the BE but not in the FE.

I think, it would make more sense to validate objects only when they are 
changed - Imagine you want to introduce a new validation rule, but you 
want to keep the existing objects untouched.
