Huh? If you mean mainstream, there's certainly a mainstreaming effect in INFOSEC. It sometimes promotes things that stop hackers. Mostly just tactical stuff that's bypassed later or thing inferior to more obscure stuff that worked with better design/architecture.

Example (paraphrased): "Dude, what's with all this separation kernel, decomposition, and interface protection nonsense? Nobody does that shit. Real hackers use a monolithic kernel with several MB of privileged code, no POLA, implementation fully in C, and some security features/apps on top of that. Do that and you're good."

Several hundred CVE's later related to the above... yeah, some things aren't popular for their actual security.
