Ok, it's a restriction in the hydraulic line that actuates the clutch. This sets a "maximum speed" at which the clutch disk can be applied to the flywheel.

In theory, it might result in smoother clutch action and less clutch wear.

In practice, it'll make you stall constantly, make it impossible to shift quickly, and generally be a pain in the dick.

Remove it.

TAKE IT OUT. There's your explanation. Seriously, just take it out.

It delays engagement of the clutch after you've completely let off the pedal. If you feel like the car shifts a little weirdly compared to other cars you've driven, this is what's causing it.

I guess that explains why it's so much more tedious to drive than the Miata was.
