The warning left me a bit puzzled. "obsolescent" is a somewhat unusual word 
The distinction is important here; see <>.

and "using" seemed like a misspelling of a request to the user ("(do) use
grep -E (in the future)"). egrep is not really using grep, but delegating to it.

Delegation is a form of use, no?

As it's not an object-oriented implementation, the technical term "delegating" has its own problems of confusion here. Other plausible alternatives I can think of ("invoking", "employing", "executing", "substituting", "falling back on", etc.) are all wordier than "using".

What do other programs do in this situation?
