Only in a very special cases. I'm writing embedded bare-metal 64-bit arm code at work right now. That is because the product needs less than 300ms boot times from power on and needs to be fast enough to do image compression (AVIF) in a reasonable time. Just using Linux and suspend would eat too much battery from the power budget. It has to have 1 year of battery life like previous generation of that same product. i.MX RT1170 with its 1Ghz 32Bit Cortex-M7 core was not fast enough so we had to jump up to much faster 64bit Cortex-A53 core.
