It's not either/or.

Elisp (and other Lisps) already had a well-developed
way to associate objects with other objects in a set:
alists.

That didn't prevent Elisp (and other Lisps) from later
adding hash-table support - an "alternative" in some
ways, but certainly not a substitute.

There is overlap, but the two are different.  As such,
each has its advantages.  It's not about "reinventing
the wheel".

It's not either/or.  Not at all.

But that's a general argument.  Whether it's worth
adding a separate command `describe-command' is a
particular question and judgment.
