It has not been hard, but it has not been done.  Why not?

{ create mytable ['] . , :noname 1+ . ; ,
  1 mytable @ execute
  1 mytable cell+ @ execute
}

This does not work.

We have had many proposals of compilation with instant execution
instead of interpretation over the years, and while it solves some
problems (e.g., ' vs. [']), it opens up others, so this has never
caught on widely.

So are I# [I#] preferable for integer literals over the integer
recognizer in the text interpreter in your opinion?  If not, why
should that approach be preferable for other cases?

Actually, applying the same principle to dealing with words, we get to
something like <http://www.complang.tuwien.ac.at/forth/colorforth-bw>.
You then write code as follows

[: gen-innerproduct [( a[row][*] -- xt )
[\ xt is of type ( b[*][column] -- n )
[\ this would be a candidate for using ]] ... [[
 _>r _:noname _r>
 ]0 ]SWAP
 _row-size _0 [do
   ]dup ]@
   _dup _@ _literal ]* ]under+
   ]cell+ _row-byte-size _+
  [loop
  _drop
 ]drop _;
[;

This means you cannot cut and paste code verbatim between
interpretation and compiled code at all, but according to you, working
around that restriction is not that hard, and the beginner might learn
something instead of having different words with superficially
identical actions hidden behind a text interpreter.

BTW, this code is an example of how malleable existing Forth systems
are even before incorporating recognizers, and in this case, even
without using a hook.  If, as you fear, Forth programmers are keen to
use recognizers to shoot themselves in the foot, they would have done
it already, without recognizers, using the multitude of existing
possibilities for it.
