execl() is not a system interface. It belongs in libc and should not have a system call associated with it.

execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic

In kernel mode, we have to duplicate the callers argv[] buffer when exec'ing new tasks. When the argv[] buffer is needed, the caller's address environment will not longer be in place

There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing.
