Personally, with the number of shuttle flights finite, wouldn't it be
better to see NASA dump spacehab flights and replace spacehab with some
of the smaller modules such as cupolla , perhaps bring back EAS ?

The Cupola is listed to go up with Node 3 on the last shuttle flight.

The Spacehab single module does make a lot of sense on the 12A.1/13A.1
missions. It allows a bit of logistics to be carried on otherwise busy
missions, when an MPLM simply won't fit in the bay, and at a time when
MPLM-based logistics flights are few and far between.

I realise that in the original assembly plan, Spacehabs were planned as
fillers because those smaller modules would not have been delivered to
KSC yet, but in the current schedule, everything is sitting in a
wharehouse waiting to be launched. So why not put a few smaller modules
in the cargo bay instead of a spacehab ?

What smaller modules? As noted above, the Cupola already has a launch slot.
