EthStaker would be happy to become a bootnode.
We are already running a public checkpoint sync endpoint and we could easily add the configuration to use that node as another bootnode.
I can be a contact point for this. Simply contact me on Discord (Remy Roy#1837) or Twitter (remy_roy) for private DMs.
