We've decided since PSR-3 that such "stock implementations" do not
belong in the spec, but can live in -util libraries. A NullCache
implementation of PSR-6 / PSR-16 would be very welcome for cache-util.

Another issue that we have now in current cache and cache-util is
complete missing of null-object.
In Psr/Log we have NullLogger, why we can't have NullCache?
There are situations, when we dont' know 100%, that there or here we
need cache. Or we know, that we need cache there, but for some time we
can live without it.
Cache could be an optional dependency. It's a bitter thought, but it's
a truth. So I suggest to add to Psr/Simple cache default NullCache as
just /dev/null or BlackWhole implementation.
Examples:
* https://github.com/symfony/cache/blob/master/Adapter/NullAdapter.php
* https://github.com/tedious/Stash/blob/master/src/Stash/Driver/BlackHole.php
Same as https://github.com/php-fig/log/blob/master/Psr/Log/NullLogger.php
Use case
Cache as an optional injectable dependency. When class user not
provides it -- we take ready NullCache and use it.

Heya,
We believe PSR-16, Simple Cache, is now ready for final review. As
coordinator, I hereby open the mandatory review period prior to a
formal
acceptance vote; voting will begin no earlier than December 1st,
2016.
Here are links to the most current version and its meta document:
https://github.com/php-fig/fig-standards/blob/1cf169c66747640c6bc7fb5097d84fbafcd00a0c/proposed/simplecache.md

The package containing the interfaces is there:
https://github.com/php-fig/simplecache
<https://github.com/php-fig/simplecache>
The latest important changes to the interfaces can be found at:
https://github.com/php-fig/simplecache/releases/tag/0.2.0
<https://github.com/php-fig/simplecache/releases/tag/0.2.0>
And FWIW, Scrapbook already provides a PSR-16 implementation in its
upcoming release:
https://github.com/matthiasmullie/scrapbook/blob/master/src/Psr16/SimpleCache.php
<https://github.com/matthiasmullie/scrapbook/blob/master/src/Psr16/SimpleCache.php>
Thanks for your time reviewing!
Cheers
