    Perhaps this is problem: The menu item shouldn't be selectable for sure
    but it may well be visible (and I'm purposely ignoring details of "how
    to grey out" for the different user interfaces).
    If it's visible (but not selectable) the user interface can provide the
    auto-generated requirements (derived from the "depends on" chains) as
    part of the "help" or where ever it seems useful. And the user at least
    knows where to look further.

    Which makes sense from the usability point of view for typical library
    functions (e.g. zlib, CRC, ...).
    But that ("which CONFIG_ variables actually selected this CONFIG_
    variable" and/or "which CONFIG_ variables will selected this CONFIG_
    variable") could also be automatically generated and displayed.
