The execlp and execvp functions have always invoked a shell if the file cannot be executed directly and are very much expected to do so. Changing this would break a huge number of applications which rely on them executing a shell in cases where the shell script does not start with #! or the system does not support #!, including every strictly conforming application that includes a shell script to be executed using execlp or execvp (since strictly conforming applications cannot use #!)
