If we had better documentation why would it be hidden?

The best documentation is the source code.  In this case, the use of
strace -p would require that you do your debugging from an account which
had the ability to access the executing pid.  If you are running inetd
from a privileged account and stracing from a user account that won't
work for hopefully obvious reasons.

Also, due to limitations in the Windows API, there is no way to strace a
forked process via strace -p.  strace -p uses the DebugActiveProcess
function and there is no way to tell the process being debugged that you
need to follow CreateProcess calls.
