UPDATE:
Tobias has replied to my support email, apologized for the delay in response time, and among other things, has said:
“I fully understand your criticism and after diving into the patches, there are indeed a few RRs where the attacks can be tightened. I have set that on our todo list.”
So even if it doesn’t get fixed, I appreciate the efforts and want it to be known I did get a lengthy and courteous reply from support about the issues. This definitely helps to ease the frustration and while I still am quite disappointed with certain aspects of this library, at least we know they’ve recognized it as being a problem instead of saying nothing is wrong. I’d much rather be disappointed in one product than be disappointed in the support team of an entire company!
Thanks @OT_Tobias!
