Not really.  After all the vast majority of undisputed fossil birds also
lack feather imprints, and yet I would argue that it would be unscientific
to portray them WITHOUT feathers as they clearly are members of a clade
whose earliest known forms were feathered and for which no definitely
unfeathered members are known.  If Mononykus is viewed as being a member of
this clade it should be portrayed with feathers, as that would be a
parsimonious prediction given its cladistic placement.  If it is NOT placed
within the clade that is another matter, and I would certainly agree with
your statement as it applies to forms like (say) ornithomimids or
oviraptorids (though I am partial to Greg Paul's feathered restoratons of
these critters - and who knows, maybe they had'em after all!)
