I for one think that layered "select" directives will open too many cans
of worms.

Best don't use select at all.

If you use it, select only options that don't depend on anything else.

If you feel that people really want you to provide a select for them which
selects something that in turn depends on other things, then I suggest you
rather let your own option depend on these lower dependencies:

config HIGHLEVEL_FEATURE
	tristate "some driver"
	depends on SYSFS  # because CONFIGFS depends on it
	select CONFIGFS
