Does/should the REPL support `--inspect`?

Version

v26.3.0

Subsystem

REPL
debugger

What steps will reproduce the bug?

Run node --inspect and node --interactive --inspect with no script arg.

What is the expected behavior? Why is that the expected behavior?

either:

$ node --inspect
node: REPL does not support --inspect

or:

$ node node --interactive --inspect
node: either --interactive or --inspect can be used, not both

similar to:

node --watch --check src/app.js
node: either --watch or --check can be used, not both

Even if it technically works, I can't see how it works in any useful way.

What do you see instead?
