You can imagine the Chancery Office wanting to uphold the bishop's authority (it is the ultimate source of that nice pay cheque) and therefore Holydays of Obligation must remain. However at the same they are a bit of a nuisance- it means those nice Conference lunches and cocktail parties have to be sacrificed on the altar of fulfilling ones obligation. Then there's the 'lay-terrh-gee-kahl' brigade in the office round the corner. They are pretty ropeable over the damage it's done to their precious cycle of Ordinary Sundays. The School chaplains, if they can get through the switchboard, will tell you that the exercise has probably halved the times any Catholic school child will go to Mass during any one year. Thankfully the Indultists have managed to resurrect some archaic dispensation to celebrate external solemnities. I suspect the score between the Bishops' Conference and the LMS stands at 1-1 at this point.
The average lay person just shakes their head and wonders what practical difference it has made. If they could get there they got there if they had been reminded. If they couldn't they didn't. I suspect this great 'easing' from our Lords and Masters has not radically increased the devotion of the faithful nor changed the amount of people attending Masses. So what has been gained? A little smug shifting of the deck chairs perhaps? An opportunity, perhaps, to get revenge on those nasty Extraordinary Form types? (Bad luck guys it backfired!). Sadly the whole exercise is more likely to have been one of deluding themselves that they are actually of some practical significance.
