Subject: ZSWAP still considered experimental?

In https://bugs.debian.org/970639 the request was made to enable ZSWAP.

Upon it was (rightly) noted that zswap.rst contained this:
> Zswap is a new feature as of v3.11 and interacts heavily with memory
> reclaim.  This interaction has not been fully explored on the large set
> of potential configurations and workloads that exist.  For this reason,
> zswap is a work in progress and should be considered experimental.

Furthermore the mm/Kconfig contains this on the ZSWAP option:
> Compressed cache for swap pages (EXPERIMENTAL)

But the contents of that zswap.rst hasn't changed since the initial commit  
61b0d76017a50c263c303fa263b295b04e0c68f6 from 2013-07-11.

Similarly, that line in Kconfig hasn't changed either since the initial commit
2b2811178e85553405b86e3fe78357b9b95889ce from 2013-07-11.

Should ZSWAP should still be considered experimental or not?

Regards,
  Diederik
