That’s not a guarantee on the Linux world either, but at least you do have the option of recompiling your distro to not use those options.
There’s talks from some distros to start dropping support for such old CPUs because it’s holding back newer CPUs that could run even faster by using those instructions.
Is it really that hard to include a fallback though? Obviously there’s a way to collect the information without that flag. I suppose if you didn’t want to take a performance hitting checking the flag all the time it could become a compile option (I would think anyone running that old of hardware would be willing to learn how to compile the kernel anyway), but there should be options available to keep the support available some how?
