The TXT is no real problem. It need not be matched, but it needs to be
normlised using form C so that everybody knows how to handle it.
There are also text in HINFO that need to use the same encoding.
In the SOA RR there are domain names that define an e-mail address, not
a host name (they are not used in matching, but are returned as data).
So not all labels can be normalised as form KC as data may be destroyed.
And text only may neither use form KC as it destroys data.
So there will be both form C and form KC in use, if we require host
names to be normalised using form KC.

But we also have the SRV RR. Here the owner name, that is the name used
in matching, is not a host name. And there may be other RRs. And the rules
for them may differ from host names. But it might not be any problem for
matching of names. We should only have one way to do matching of
owner names, independantly of type of name (like host name, service name).
