FPUs - yes.

In the early 486 days, Intel had big troubles, and a lot of competition - but they moved ahead with the Pentium fast enough to save their world.

There was no demand for the SX before Intel started selling it - the major point of the 486 was having the CPU and FPU on the same die. Disabling the FPU, so as to be able to sell the chip for less, was definitely not part of the original plan. The sequence of events was 1) Find defects in FPU, 2) What do we do with this crap, 3) Try to sell what's left at a discount. No. 3 worked - low-cost PC makers liked it, sold SX machines as a cheaper upgrade from the 386.
