Folks, the XMPP community has not chosen NFD, the XMPP community is
considering whether to choose NFD or stick with NFC as is done in
IDNA2008. The discussion in this thread is valuable input that will help
educate the XMPP community, and perhaps others, regarding the costs and
benefits of NFD vs. NFC. So I say thank you for the input while I work
to socialize these insights in the XMPP community.
