Well, there is harm in that the documentation is lying to developers. The documentation states that “if you enable strict types, you will get strict types”. Developers write code building on that assumption. If the documentation/samples are wrong, they need to be changed immediately!
Note: I’m not talking about mixed precision here. I’m talking about single precision. As a developer, I want to make sure all my layers run e.g. in INT8. So I enable INT8 and set Strict Types. If this is not enough, your documentation needs to clearly state what else I need to do to achieve that.
