I understand the intent here, and would be very ideal for us as a project
if we achieve it.

Two concerns I have to make it a necessary condition to release  (or some

* Do we (as developers) aware of glusto framework and how to write tests at
this time ? If not, this activity itself may take some time, and we are
sure to miss the deadline.

* Is the glusto framework ready to get contributions?
  - I may be naive in asking it, but how easy is it to add a new feature
into it? specially something like GD2 (which is a core part of Gluster
4.0), or a feature like reflink which touches most of components, but is
technically just 1 of the 50 fops we have?

Also we did ask this question or suggestion to have 'line coverage' report
with you new component along with the feature to get the feature called
'supported', and I don't think any one signed-off on that.

Here is what I am thinking:

* Add as much as possible feature to 4.0, start with marking every one of
them as 'experimental'.
* Move them out of 'experimental' bucket once the test cases are added.
* Aim to get most of these features out of 'experimental' by adding more
test cases before release of 4.1/4.2 (which ever is going to be our LTM

This way, we get to keep the 4.0 release promise (both on features and
timeline), and by our LTM, we can say which of it is 'recommended', and
which is not.

My 2cents.
