I must be missing something, on the Aircraft I fly 75 / 67 unless you are doing 8-10 knots in a 90 degree turn at heavy weight you will slowly come to a stop.
Around 8 knots will take you smoothly round a 90 degree turn onto the runway with no great stress (providing you are smooth) so there you are, not having wasted any runway with 10 knots already 'in hand' you can advance the power a little before alignment enough to be equally spooled then straight to take off power once lined up.
Best of both worlds, useful momentum in hand with take off power set and no runway wasted
