PUP-5: Whitelist batch of new blockchains in the SupportedBlockchains Parameter

Getting a significant amount of nodes onto a new chain requires either:

  • those nodes unstake and re-stake, losing their income stream for 3 weeks and possibly affecting network quality due to nodes going offline
    or
  • stake new nodes, exacerbating the # of validators issue

Could you comment on a possible timeline for an UPDATE STAKE command?
