The consequences of removing pclntab would be fairly severe. You wouldn't just lose runtime.Callers and stack traces and tracing and profiling. The pclntab section is also used by the garbage collector to traverse the stack, and by the stack copying code. I doubt that many substantial Go programs would still work correctly. That said you could in principle drop part of pclntab with less severe consequences, such as removing the function names. I don't know of any supported way to do that, though.
