I wonder how many registries would really want to do this. It sounds
very dangerous. 

However, the load on the TLD servers could be greatly diminished
by adding a TLD TXT record with a very high TTL.

I am not saying it's a solution to the problem. Just yet another hack.
The application should never query the TLD servers (nor lvl 2 for e.g.
.uk) for SPF-records of any kind.
