Indeed. Some of the issues end up just becoming compiler flags, which
means that anything that uses C is "tainted" by the processor choice. And
happily there isn't all that much non-C in the kernel any more.
One thing we _could_ potentially do is to simplify the CPU selection a
bit, and make it a two-stage process. Basically have a
bool "Optimize for current CPU" CONFIG_CPU_CURRENT
which most people who just want to get the best kernel would use. Less
confusion that way.
