I enter data into DNS by loading it from a zone file. And I do not
want that data to be as I enter it. If I enter a upper case letter, then
I want it to be returned in responses.

If INDRA also defines that the zone file must be loaded and changed after
nameprep, you are right that all data is already in nameprep form.
But it is unacceptable for me that data is changed when the zone file
is loaded.

In todays DNS the case of letters are preserved, but during a comparison
case is not significant. The correct case is returned in responses.
There is no destruction of data.
