The explorer lists only chains that have an explorer

SPC, Pars and Osage have no explorer and no public node, the devnet has no
explorer, and the Hanzo testnet explorer has no DNS name. Their registry entries
put links to names that do not resolve on every page (the "SPC L1" and "Pars L1"
cards, the chain switcher, the network selector), and the Pars entry sent a
node request to api.pars.network on every page load that failed with 502.

The P-Chain still lists SPC and Pars; their cards render without a link.
