I don't see it. What does the same namespace give you? So you see in the code a bunch of ifdeffery and some or all of them have CONFIG_MITIGATION_ prepended. To me it doesn't matter whether they're mitigations or not - it is just the next Kconfig symbol.

Apparently there are use cases where people simply want to disable all that mitigation crap because they want their performance back. This thread being one. And I know of another one with a similar sentiment.
