We may eventually do this or at least expose some of the more important fields, however, unfortunately just exposing NodeAnnouncentInfo as is doesn't play well with our bindings. I'm also on the fence if we shouldn't rather expose APIs to query the network graph generally, as this would provide even more utility and can be helpful for debugging purposes.

Yeah the main thing we were going to use this for was getting the alias, maybe that'd be better to add here instead

Mhhh, so generally we're in the process of including some more fields in the RGS data, mostly to fix BOLT12 compat issues for RGS users. However, alias likely won't be included to keep the snapshot size small. So the only nodes having it available would be P2P nodes, i.e., exactly not the client-side nodes that likely would want it to show connected nodes in a nicer way. For fully-synced always-on nodes it would make more sense to access the network graph generally, which we should expose eventually.
