I considered it when ds9 had such a bad second year at school his toilet training regressed. I didn't do it because I am a single mum who has to work and didn't earn enough to pay someone to care for him or have free care available. I carefully monitored the next year and sent him to a one day gifted programme each week (which I also couldn't really afford). I also stepped up at home learning. Ds is a sporty child and enjoys lunch breaks so school is mostly OK (so far). He has one more year of primary and I am making plans for intermediate now.
I am too disorganised to homeschool well anyway.
