As a physicist, I see your point but I believe you are mistaken in
principle. Velocity is indeed a vector quantity, but it is a vector in
the parameter space you are considering. In our 3D world, velocity
vector is a time derivative of the 3D displacement. In the bugzilla
case, the system variable is scalar, so velocity is a scalar too.
Normally, speed is the absolute value of velocity---one has to work hard
at teasing it out of simple-to-get velocity; in this case they just are
'bug velocity' just rolled off the tongue, simply because 'bug' is
monosylabic and it somehow created a nice 'foot'. 'bug speed' sound
awkward to me, although I kind-of like 'bug rate'.

Please don't mix my work in it. I don't speak for them, and they don't
for me, especially on Fedora issues.
