yet another line width bug - no switch interpolation?

[BA]

ok, i've never gotten any response on any of these line width bugs i've posted, but might as well give it a shot -

i just noticed something strange... i have a switch layer with interpolation on, and it's all working fine, except the one thing that isn't being interpolated is the line width.

wondering if it's something dumb i've done, or if that's just the way it is. which would seem strange, since smoothly switching between different line widths is a useful ability.

try it yourself with a simple test. doesn't seem to work, does it? or does it???

Line color, point curvature and fill color don't interpolate either, only point motion, it seems. It would be nice if all these animation channels were interpolatable with switch layers, just as point motion is.
