I think you misunderstand.
PSR-6 *does* meet some developer needs. PSR-16 is to optimize for a
narrower-but-common use case. They complement each other. That's fine.
Neither PSR-6 nor PSR-16 (nor PSR-7 for that matter) have
implementations included in the spec or in the Packagist package. That's
fine. For basic implementations for which there's no reason for
everyone to re-implement them (eg, Null cache), or portions therein, we
offer -util packages. It currently doesn't include a null
implementation of PSR-6 or PSR-16. Adding one would not be difficult
and (speaking as the nominal maintainer of the cache-util package) would
be very welcome.

Larry, this approach is overcomplicated.
NullObject of any interface can be implemented in single simple way.
My PRs in OverComplexCache are still open and I dont' believe it would
be merged.
So let complex things will be in complex PSRs and simple ones in simple.
As I understand current PSR/Cache is not meet developers needs, so
that we have SimpleCache PSR here.

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/symfony/cache/blob/master/Adapter/NullAdapter.php>
*
https://github.com/tedious/Stash/blob/master/src/Stash/Driver/BlackHole.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
<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
