or the countless 32-bit Raspberry Pi?

my xPack binary tools, which include qemu arm & qemu riscv, are also available 
for arm 32-bit, and the analytics show about the same number of downloads for 
32-bit as for 64-bit.

given the current chip shortages, I estimate that the 32-bit Arm binaries will 
still be useful for a few more years.

I concur, please do not intentionally break support for arm 32-bit, this will 
make a lot of unhappy users, who currently have no choice to upgrade.

thank you,
