Why expose the end-user to implementation details like "been tagged with the 'maturity' directive"?

Maybe you rather want
bool "Allow to select DEPRECATED features."
because MATURITY_DEPRECATED=N probably means "Do not allow to select DEPRECATED features" which implies that deprecated features will be deselected. In your wording, MATURITY_DEPRECATED=N would be just "Do not display DEPRECATED features" which is probably less than what you want it to be.
That said, I don't know if the approach is going into the right direction. For example, the way you are starting it requires updates to all Kconfig UIs/scripts, to work correctly. Otherwise, users could select ACTIVATE_MATURITY but the tags would still be ignored.
Another approach could be to - continue to use "config EXPERIMENTAL" and "depends on EXPERIMENTAL" and extend it for OBSOLETE, and if you cannot resist, for DEPRECATED, - extend interactive UIs like xconfig and menuconfig and oldconfig to display an EXPERIMENTAL sign alongside the title of an option which depends on EXPERIMENTAL, - delete occurrences of the string EXPERIMENTAL from titles of options and help texts, - vice versa for OBSOLETE, and if you cannot resist, for DEPRECATED. This does what you want while it keeps contents separate from presentation and avoids to extend the Kconfig language. A simple Kconfig language without presentational ballast allows for creation of a multitude of fine-tuned configurator UIs/scripts, which can be extended by all sorts of features, e.g. better support in dealing with obsolete configuration options. -- Stefan Richter -=====-=-=== -=-- ===-= http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
