I think in the earlier phase when properties are changing a lot, you also are developing on quite fast pace, and not having much of a really persistent data, and that it's ok to wipe persistent data for each development cycle.
When I say "early" I mean maybe for the first year of the project, depending on how long the project is. And you might go live quite early (if you follow "release early, release often"), in which case production data will have to be dealt with. So that's not really an assertion I can agree with.
I don't see much more (performance) overhead in saying qName.name() than qName.toString() when storing entity to database.
I tried exporting our database to JSON, and then compared one typical object before and after QNames. Without: 1240 chars, With: 2920. So more than double with QNames. I would say that's quite significant.
