The commit made the wrong assumption that 64-bit distros are most common these days on arm devices, but as Liviu Ionescu pointed out, the recommended OS for the very popular Raspberry Pi boards is still the 32-bit variant, and thus likely still used by a lot of people: https://www.raspberrypi.com/software/operating-systems/ Thus it's likely still a little bit too early to put this host environment on the deprecation list and we should wait a little bit longer 'til 64-bit distros are the predominant ones.
