yes you are basically correct. CFINT (or rather one of its friends)
also serves to slow down "smaller" server models (even without
using interactive). The traditional arguments for this are:
1) it makes sense for IBM to use basically the same processor
no matter what the model (cheaper to manufacture one than many)
2) you get what you pay for.
3) IBM has to compete with Sun/HP/Intel in the server market so
the pure server machine has to be cheap enough to compete, and
green screen loyalists are captive anyway and can't go anywhere else
so why not sock it to them. The subtle message is that IBM wants
you to get off the iSeries and on to the pSeries.

Makes sense?
