I realize that NIST tables are almost identical to BIPM, but this is
like saying that a slightly modified copy of a document is almost
identical to the original. In my understanding BIPM still the
authoritative source, and NIST is an adaptation done by USA for their
own work (even if they intentionally try to stay close to the original).

The same could be said about other quantities, for example "PlaneAngle"
versus "SolidAngle". But since "Angle" is widely understood as plane
angle, it seems safe to use the simpler term.
I think that a similar reasoning could be applied to "density". During
my 3 years of studies in physics at the university, I do not remember
having hear "mass density" for the quantity of kg/m3. For what it is
worth, a search on Google give:
physics "mass density": 537,000 hits
physics mass density: 115,000,000 hits (note the absence of quote). A
quick view of the first hits show that they are really talking about the
quantity of kg/m3.
Even if other kind of density exits, I think that "density" is widely
understood as "mass density".
