Select different versions for different architectures?

[stumpylog]

For the moment, my project supports armv7l machines, and relies heavily on piwheels to build wheels for that architecture.

I'm trying to come up with a version string that would allow me to lock package versions only for armv7l, so it can track whatever latest piwheels has built, but allow x86_64 and aarch64 to be unlocked. I have no idea if that's even possible?

Something like this syntax would be the ideal:

scipy = [
	{version = "*", platform_machine = "== 'x86_64'"},
	{version = "*", platform_machine = "== 'aarch64'"},
	{version = "==1.8.1", platform_machine = "== 'armhf'"},
]
