I'm somewhat concerned about the ensuing compatibility :) It seems like vendors have 4+ options right now.
* IDNA2003
* IDNA2008 (no mapping)
* 5895 mappings
* UTS#46 mappings
It is unfortunate that there's this much confusion.

And, obviously, RFC 5895 provides a different, less aggressive,
model. I suggest that people should look at both and then make
whatever informed decisions suit their needs.
