Right, host-python is a dependency of all those things indeed.

Because we don't enforce this for host packages. We do enforce it for
target packages (i.e a target package cannot be built if its Config.in
option is not enabled somehow). But we don't enforce it for host
packages.
For example, host-pkgconf has a visible Config.in option called
BR2_PACKAGE_HOST_PKGCONF. However, almost none of the packages that
depend on host-pkgconf have a select BR2_PACKAGE_HOST_PKGCONF.

See above: only for target packages.

I don't really understand why your host-python package fails to build.
Could you share the entire build log of the host-python package ?
Best regards,
