I hear you when you note that the technology has changed, and "frost free" freezers remove moisture instead of adding it. But we haven't determined yet if it's the addition of moisture or the act of freezing that is providing the beneficial help for the thread, and it sounds like it's the freezing alone. If you're concerned about adding a bit of moisture, you could always do as I did, and freeze it in a container of water, or not as drastic, just a sealed plastic bag with moisture in it.
That would solve the problem.

This is not the first time I've heard it suggested that I put some kind of material into the freezer - dry or wet - for at least 24 hours to obtain a beneficial result. I'm thinking there has to be something to it. If it works, then I say "go for it!"
Why argue with success?
