The Nouveau graphics driver have a nice feature matrix on it's
webpage
and I think that BTRFS perhaps should consider doing something like
that
on it's official wiki as well

BTRFS also has a feature matrix. The links to it are in the "News"
section
however:

I mentioned this matrix as a good *starting* point. And I think it would
be
easy to extent it:

Just add another column called "Production ready". Then research / ask
about production stability of each feature. The only challenge is: Who
is
authoritative on that? I´d certainly ask the developer of a feature, but
I´d also consider user reports to some extent.

Maybe thats the real challenge.

If you wish, I´d go through each feature there and give my own
estimation.
But I think there are others who are deeper into this.

That is exactly the same reason I don't edit the wiki myself. I could of
course get it started and hopefully someone will correct what I write,
but I feel that if I start this off I don't have deep enough knowledge
to do a proper start. Perhaps I will change my mind about this.

Well one thing would be to start with the column and start filling the more
easy stuff. And if its not known since what kernel version, but its known to
be stable I suggest to conservatively just put the first kernel version
into it where people think it is stable or in doubt even put 4.7 into it.
It can still be reduced to lower kernel versions.

Well: I made a tiny start. I linked "Features by kernel version" more
prominently on the main page, so it is easier to find and also added the
following warning just above the table:

"WARNING: The "Version" row states at which version a feature has been
merged into the mainline kernel. It does not tell anything about at which
kernel version it is considered mature enough for production use."

Now I wonder: Would adding a "Production ready" column, stating the first
known to be stable kernel version make sense in this table? What do you
think? I can add the column and give some first rough, conservative
estimations on a few features.

What do you think? Is this a good place?

It isn´t as straight forward to add this column as I thought. If I add it 
after "Version" then the following fields are not aligned anymore, even tough 
they use some kind of identifier – but that identifier also doesn´t match the 
row title. After reading about mediawiki syntax I came to the conclusion that 
I need to add the new column in every data row as well and cannot just assign 
values to the rows and leave out whats not known yet.

! Feature !! Version !! Description !! Notes
{{FeatureMerged
|name=scrub
|version=3.0
|text=Read all data and verify checksums, repair if possible.
}}
