I get the vibe a lot of these critiques are rooted in academic understanding of the issues rather than real world practice. In practice, these are all problems that can be addressed...some rather trivially. The biggest real world concern I've ever had with embedding incremental IDs into URLs is that incremental IDs can leak information, like how many records you have and how quickly that's growing. Depending on your business, you may want to obfuscate that.
