So yeah... as far as I can tell, there are multiple ways to approach
this issue, but none of them seem straight forward nor pretty. Bitbake
as it is is just fundamentally not good at handling highly dynamic
configurations. The combination with KAS somewhat defuses the
situation, but there are still some situations where there is no easy
answer.

Yes, yocto does not support 'variations' of the build that is already set
up. Once you set the distro, and the machine, there's only one way to build
a recipe; if you want another way, you need to indeed make another recipe,
or another distro. I would still say making a set of distros is still the
proper 'yocto way' to solve your problem. There are examples in meta-poky:
poky-altcfg and poky-tiny, and there has been poky-bleeding-revisions or
similar in the past.

This is a reoccurring topic; there have been proposal in the past to
introduce 'variants' as yet another abstraction, but they add so much
complexity on top of what is already very complex, that the tradeoff is not
acceptable to the project.
