Binary as commented out vs set to y

But some Kconfig options are used as strings, so one could be set as:

CONFIG_SOME_OPTION="something"

and another could be unset as:

CONFIG_SOME_OTHER_OPTION=""

That's what I meant.

Yes, I understand.

In the end it's a decision on the trade-off between having a terse
directory and file layout vs. giving 1st time users something that
works out of the box.

As 1st time user I would obviously go for the latter :-)
If there is something that _is_ expected to work, it reduces the
problem space I have to debug when I experience a failure.
