So everyone should have to deal with removing an unnecessary support structure because a few people have adhesion issues. Again, you can very easily add a brim or adhesion disk yourself. If you don't want a full brim then add the disk in meshmixer or literally any other similar program. Even tinkercad could do this fairly trivially.
I never said adhesion disks didn't weren't useful, I didn't even say they wouldn't be useful with this model, but claiming that if they aren't included in a model means it isn't designed with fff in mind is just silly. You're expecting a minor problem that a small fraction of users experience be solved by the model designer.
Support structures of any kind should be an end user addition. Otherwise you're inconveniencing everyone that doesn't need them. If you can't understand that then you're the only one in denial.
