Because of ignorance and laziness.
Just tried "%#o" with v3.4-rc5-182-g71eb557 and got equivalent results
to "0%o", including 0->"00".

So it's agreeably better, even we just don't see it yet.

Oops. I don't have a killer argument.

We happened to look for the information for a running service and
couldn't think of a simple, non-invasive solution.
It feels like it'd be useful to expose it.

I assumed status is a good fit (already has euid, egid and ngroups for example).
AFAICT there wouldn't be any significant security or performance implications.

But I could very well be missing something.


Thanks,
