It's very convenient to see what properties and their values
are currently being assigned in the registered software nodes.

Show properties and their values in sysfs.

No, sysfs is "one value per file", and that is not what you are showing
here at all :(

It is following: it's a "one value" for property in question,

As we may read in [1]: "...so it is socially acceptable to express an
array of values of the same type."

And here is exactly the case: *values of the same type*.

So what is it going to look like exactly?  And what tool is going to be
there to parse this mess?  Who is going to to use it?

Arrays of data are not "one value".
