No you are right, as the splash screen says it is an experimental
service. But I am an LC employee and I did the work using the LCSH
MARC data. The goal is to have the RDF data continuously updated based
on the LCSH/MARC update files. Whether this service would live at
lcsh.info or elsewhere isn't currently decided. I'm not sure the
SKOS/RDF will ever be authoritative compared with the MARC.

If lcsh.loc.gov came online tomorrow and all the concept URIs at
lcsh.info redirected appropriately to lcsh.loc.gov would that count as
persistence? What does "maintained properly" mean in this context?
Isn't lcsh.info just used as an example, not as an instruction to use
concepts from that concept scheme.

Oh there's lots you could use: dbpedia [1], geonames [2] opencyc [3]
and more [4]. But perhaps these don't meet your criteria for being
real either? I'm not really suggesting that GEM vocabs not be
used--they seem excellent as well.
