Imeo. If you need to charge a couple of euro for peace of mind, I don't have a problem with that. Typically I say if it's defective, then it should be free. But some don't have a GG base to test and will never know if some day they pick up an ody and a year later say "damn I wish I took one"
I have a slight varying degree of thread issues on my 3. So I would spend the 1-2 euro to have peace of mind.
If somebody doesn't need them, that's fine. But if someone decide later "I wish I had it because it doesn't fit" they would be sorry.
My thoughts on this. If you want exact count, run a preorder for a few days. You'll know how many want this.
