Yes, I have considered it.
But doing so would require me to add about 20k sysfs attributes.
For no apparent gain.
So I've settled on this condensed approach here.
Hello Hannes,
My understanding is that the one-value-per-file rule was introduced for
sysfs to make it easy for software, e.g. shell scripts, to process that
information. If multiple values occur in the same sysfs file sometimes
complicated code is needed in shell scripts to parse these values. If
one value is present in each sysfs file it becomes much easier for
software to process that sysfs information.
Bart.
