Pinning is very complex, there is always the chance that you forget to update the pins and perform a denial of service against your own users. At the point where the device itself is compromised, you can’t really assert to anything. Furthermore, there is always the risk that your developers implement pinning incorrectly and introduce a chain validation failure.

Lots of apps use the anticheat/obfuscation mechanisms added by mobile apps are also trivial to bypass using instrumentation - ie frida codeshare. I know you aren’t implying that people should use client side controls to protect an app running on a device and an environment that they control, but in my experience even some technical folk will try and to do this
