No, the problem we have now is exactly this one, because at the place where
we try to fetch the bytecode, all we have is a byte-code-function-p
object (i.e. what indirect-function returned above). In many cases,
this object was found in the symbol-function cell of a symbol, but we
don't even currently try and propagate this symbol to the fetch-bytecode
function, so while in theory it's stashed somewhere up in the stack we
don't currently have any way to recover it.
In any case, I think deprecating byte-compile-dynamic is a better
solution than trying to fix its many shortcomings, since I don't know of
any concrete evidence that it has any real benefit.
