If anything it'll give you slightly fast load times due to the lack needing to have the PS.com URL redirect you to the Lithium server.
Thankfully I already contacted my friends at Lithium and had them shut down the wormhole generator on that URL, so no worries about falling into an alternate dimension. So ya, aside from that, nope, nothing changes.
