It's an instrument among others.  It's not particularly reliable.

One more time.  The user hook for 'foo-base-mode', which is the
normal parent of 'foo-mode', 'foo-ts-mode' and 'foo-whatever-impl-mode'
can be used to:

* setup a  library of snippets for the Foo language.;
* define a suitable Flymake backend for said language
* appear in dir-locals to setup fill-column for this language
* define simpler more robust major-mode database, such as

((foo-base-mode . thingy-42)
 (js-base-mode . thingy-43)
 (ruby-base-mode . thingy-45))

* many more things

These are exactly the things being discussed here.

There is this crystal clear evidence of usefulness being laid
in front of you and yet you claim adamantly it is "completely
useless".  With no justification for the statement.  Because
of course, there is no such thing.
