TBH, I have no special requirement for this option to be set and now,
looking at Kconfig entry for this option, I think that I got it here
because I stated configuration with allnoconfig.

OTOH, I don't see how harmful it can be since description says:

          This option should be enabled if compiling the kernel for
          an embedded system so certain expert options are available
          for configuration

yes, it selects CONFIG_EXPERT and that had side effect that, for
example, CONFIG_NAMESPACE could be compiled out.

Have I missed something around it?

Thanks
Vladimir
