Improving readability is not a silly idea and I never said that. Rather,
the cost of what you're trying to accomplish, needs to be weighed.

The final goal of this is, AFAIU, finding whether a feature flag is
there or not and you can use grep for that now, on *any* kernel.

And if you need the feature flags sorted, you can do that too:

$ grep -m 1 flags /proc/cpuinfo | tr " " "\n" | sort | xargs

and there probably is even a simpler way to do that.

Or add a shell alias for that or a small script or ...
