No consideration. The current lateral sector boudaries vary only slightly (if at all) from the pre-TAAATS/Flight Service days. The biggest change was in the sectors outside the J curve, mainly because it was difficult fitting a long skinny sector on a rectangular screen. The current low level sectors use the old FS frequencies that were under their pre-TAAATS CTA sector ancestor/s.
Resectorisation seems to be an issue that's in the 'too hard' basket i.e the cost and man-hours involved in training, system upgrades, new charts and documents etc. is prohibitive.
