You are correct. The addition of a shim creates "more than"
proper bee space between the two supers, if one had proper
bee space to start. Not to worry... yes it is a massive
violation of "bee space", but the idea here is to put the
shims in place for the flow, and remove them with the supers,
harvesting soon enough that the bees have no time to make
bridge comb.
Use of Imrie shims carries several inherent assumptions
which may not be true for every beekeeper, and/or may not
be understood to be inherent assumptions:
1) You need a good supply of drawn comb. Putting shims
between supers of undrawn foundation is just asking
for a terrible mess. A shim can be added once both
supers are drawn, but I would not do so before drawing.
(Of course, this just may be my cognitively-challenged
bees, yours might be better about drawing the foundation
before drawing random comb in every other possible space...)
2) You need to harvest early and often, to pull supers
before bridge comb gets built, and you need to
extract quickly so that you can slap the extracted
supers back onto the hives while the flow continues.
There is no use to using shims to "increase the speed with
which nectar is harvested", and then not take advantage of
"faster" as a beekeeper.

Sure, you could do that, shims are just a way to avoid drilling
holes and blocking the holes when they are not needed. Shims
also provide a smaller opening, one that is easier for the bees
to defend in the event that robbing gets started. (Of course,
point [2] above assumes that you aren't going to let the honey
stay on the hives long enough to allow bees to get in a robbing mood.)
