Yes, but I don't think that it would help for the fake bold issue.
You can't expect users to add such specials when using fake bold

If I understood the code you are basically inserting "0 Tr" when the
fake bold font ends. This should imho work for the fake bold
problem. In most cases it shouldn't harm Alexander's code. But it
could perhaps do harm if such an embolden is used at the wrong
place. I can't test with xdvipdfmx, but there is for pdflatex a
package called pdfrender which does something similar: it adds 2 Tr
and 0 Tr to embolden a font. And if I use it inside the \href the
