Entity and Block Entity NBT

[gentlegiantJGC]

Is there any way the entity and block entity support could be extended to extract the default NBT values. It would be very useful to programmatically extract this information.

I have had a bit of a look but it is all rather difficult to understand (I have knowledge of python but not java)

Looking through the disassembled code it might be possible if you trace back the extension declarations and scrape each file but I think it is a bit above my level.
