Oh wow. And all of this just convinces me that we should _not_ do any
|
|||
|
|
of this, since clearly it's all totally useless and people can't even
|
|||
|
|
agree on a name.
|
|||
|
|
|
|||
|
|
Let's wait five years and see if there is actually any consensus on it
|
|||
|
|
being needed and used at all, rather than rush into something just
|
|||
|
|
because "we can".
