I disagree.  For all practical purposes in standard classical music,
enharmonic equivalents *do* sound the same.  What you are referring to
IMHO is a special case that might be controlled by a flag.

As mentioned above: This might be controlled by a flag.  Or maybe a
special “E12_tie_slur” engraver can handle this.
