Thank you for supporting our efforts to minimise the parts library "bloat" by
not asking for this duplication of basic parts. In this case there is nothing to
prevent LDraw modellers from placing a plume where it could fit into the tiny
hole in an underside stud3.
We typically use the "non-functional" argument to avoid having to model the many
slight changes made to basic bricks and plates over the years - many of which
improve the clutch or reduce the ABS, but are less than 1LDU in size and the
presence or absence of which have minimal effect on the rendered model.
I'd prefer parts author effort to be directed at increasing the overall breadth
of the library, rather than increasing its ability to capture minute variations.
It's a subjective decision, of course, and I wouldn't claim that we are always
totally consistent - just trying to steer a middle road.
