I don't regret topping up my SA and transferring OA to SA to hit FRS early. Still get to earn higher interest and compounding effect over the years up to age 55. But have to re-do my retirement planning 55 onwards. Quite a big impact.The removal of SA at 55 doesn't change the fact that SA still pays 4% until 55. Sure it causes some change in assumptions in retirement planning but not sure whether all the whining about previous top up or transfer to SA are justified
