If you want \mathbf{Var} to "look OK" then you need to kern the V and a

inserting
kerns where needed. (but maybe luatex and or xetex can modify the font

at font loading time?
i think maybe the "proper" thing
to do is recommend declaring these
multi-letter non-\mathrm strings
as a special kind of operator name.
may require a new command ...
i agree with david that the text
kerning is definitely wanted here.
