This is indeed what you have to do, arcgrid files are otherwise
un-referenced,
end up with a "EPSG:404000" (a joke on HTTP 404) and mosaic in older
versions of GeoServer could not handle that. Check out 2.14-RC, that should
mosaic files without georeferencing... althought I'm guessing it's not what
you want.

Also, I'd recomment not to use ArcGrid sources for anything but small
experiments,
reading from text files is slow.
With no requirements against it, I'd gdal_translate everything and add a
CRS into
in the process.

I believe it does not, and was never meant to. Is the documentation
suggesting that it should?
Maybe there is a misunderstanding on "MosaicCRS", which is the "mosaic CRS",
not the granules one, and it's used when you have multiple crs in input
(as we it has to pretend the mosaic to be uniform, it needs to know which
one to use).
If this is the one, could you please suggest how to reword its description
to avoid confusion?

I suggest not to use website, if you check on the home page it states at
the bottom:
 "Last update: 2013"

The link you are providing does not work, did you use this?
http://spatialreference.org/ref/epsg/28992/ogcwkt/

Also, there is millions of ways of "does not work", did not work how?
