Yes, it seems that you can just add a dummy value.

Ah, this reminds me to rectify one remark:

This was faulty memory of mine: They actually use a special version of
TT interpreter (it's a patched version of the MS interpreter), but
stem darkening and embolding takes place *after* hinting.
The darkening amount, however, needs to be fractional. The Adobe
people implement this by disabling hints in the x-direction (which is
disabled for the LCD mode anyway), applying darkening only in the
x-direction.
