iproute2 - one line mode should be deprecated?

[Stephen Hemminger]

The one line output mode of iproute2 commands was invented before I was involved.
It looks like the only real usage is for scripts to consume the output of commands.
Now that JSON is supported, the one line mode is just lingering technical debt.

Does anyone still use oneline mode?
Could it be removed in some future version of iproute?

There are still output format bugs in oneline, and some missing bits
of JSON support as well.

I'm terribly old-fashioned myself and still use one-line mode, and the
kinds of scripts I use still use awk. I may be the last one standing
here...

I use oneline a lot as well for a quick list of netdevs and network
addresses.

Either that or diff as well as socket list ('ss') here.

I'm probably < 50 vs > 50 between plain 'ss' output + masochistic awk
and one line output + gory grep/sed/cut ('ss' does not even produce
json).

'ss' oneline output option differs from 'ip' one: it does not help using
either imho :o/

Deprecation then removal won't hurt me.
