[Typo3-dev] Database Relation fields and recursive/cascade delete of records?

Yes, I thought about this...
Is TYPO3 core complant with such changes to ext_tables.sql?
But still problem - what if records has "File" fields, or something resources,
for which DB is not responsible? I think should be callback code to do
any stuff.
