Agreed, but as John points out, it *was* legal (intentionally or not)
so this is a breaking change for some people.
Being a breaking change, I would vote for backing it out until
something can be decided that will not break existing systems.
Is there any value that current is not valid in a key that would work
instead of a dot?
Keep in mind though, that this is not a new Hiera 1.3.x. It's not even
1.x. It's 2.0.0. If there is any point in time when we want to make a
statement on what characters that are legal when declaring a key in
Hiera, that time is now.

I think perhaps if the issue could be pointed out that
provides for *key* interpolation on dotted values without
interpolation notation, that might clear things up.
Thomas' example does provide HI-14 as I read it *but* there
may have been an unintended side effect that the following is
a disaster for exsiting sites:
my.days_up: "%{system_uptime.days}"
my.days_up will try to traverse into the data structure of
'my' and will break. This is bad. Nothing should be
interpolated that is not surrounded in "%{}"
I think that whether declaring a value with a dotted key is
considered legal or not is a separate discussion. If that's the
case, then we can't use dots to traverse. Not when looking up and
not in interpolated expressions (since that's an implicit lookup).
