Any suggestions for whether that is achievable without a fake datastore, or
other things I should look at?
Following up with Jody, I see three ways:
* Fake datastore, the most visible downside of this approach, that I see,
is that you'd have to play with styles to get what you want,
and might need a rendering transformation if you need to place
the labels at the map border. But it also has upsides, since it's a
true data source you could use it for WFS (someone in need of a
grid to download) and WPS (compute stuff over a regular subdivision)
* Map decoration like Jody suggested. Downsides, it's not a WMS layer
anymore, it's something that you have to configure as an admin, and
include it into the map output by adding a vendor parameter to
choose the desired layout, so it won't work with shrink wrapped tools
* The "high path" would be to roll a new type of Layer in the configuration,
and teach the whole GeoServer how to use it. See the work that was
done, back then, to add WMS cascading as its own custom layer.
The new layer could wrap what Jody's DirectLayer, and could be
made extensible to allow any kind of direct layer to be configured (grid,
or otherwise).
The minimum workable set here would be to add it to the configuration,
persistence, REST config, and WMS subsystem.
I think all the three paths would be welcomed, of course the last one, the
fancy one, could open more extensibility for the future... but it's also
quite
a bit more work I'm afraid.
To give you a reference, when I added WMS cascading to GeoServer,
with a WMS client already available in GeoTools, I had to work for five
days like a madman, no distractions, some overtime (and back then
there was no policy to add tests for everything, now there is).
