I would call it an incompatibility bug ;-)

As others have noted, some ligatures in letterspaced text shouldn't be 
broken. If \letterspacefont now disables all ligatures, this is no 
longer possible except by changing the font for each and every such 
ligature (and even for "--", "<<" etc.). This renders \letterspacefont 
basically useless.

And to consider the fact that \tagcode and \pdfnoligatures are virtually 
no-ops as an incompatibility sounds like a strong euphemism to me...

Of course, one could always use lua code, but if you provide the pdftex 
commands at all, I think they should function in a sensible way.
