It cannot be incorporated in GeoTools indeed, which is were datastores
normally reside, but I believe it could be incorporated in GeoServer,
which has a GPL v2 or later licence.

Datastores and extensions living outside of the GeoTools or GeoServer code
bases have a difficult life, GeoServer
moves relatively fast, a datastore that worked fine a couple of years ago
might not work anymore due to various
changes, library upgrades and the like. The ones that are kept in the main
codebase get migrated as we perform
the changes, the others are left out in the dust.
That's not to say it's not possible to keep a store out, GeoMesa for
example is doing it fine, but it's probably the one
exception in a landscape of external extensions that used to work at one
point, and do not anymore today.

That said... the error seems to hint at a missing dependency (a missing
jar):
" Caused by: java.lang.ClassNotFoundException: org.neo4j.graphdb.
GraphDatabaseService"
