I am not a real user of ARM 32-bit. I just checked information for ARM
32-bit (armv7) use cases.

It seems that the version 1.1 is the last model for 32-bit, and the
announcement was 5 August 2015.
I assume a considerable number of people using ARM 32-bit Raspberry Pi.

## Running Linux on smart phone device.

Some articles about it.

ARMv7 (32-bit) was 98.1% in entire share of android hardware on March 2017.

For example, how about releasing compat-qemu50 RPM if upstream will
drop armv7 on qemu 6.x?
It's like compat-openssl10 RPM for openssl (version 1.1) RPM.

Maybe if some RPM packages need armv7 support, they can use
compat-qemu50 conditionally in the spec file.
