These changes don't make sense to me, These changes work in your local?
i see Cannot find module '@snapshot-labs/score-api' or its corresponding type declarations.

There is not much in the original issue description but ideally, it should be like this:

• Make it impossible to select this strategy in space settings on UI and hub
  as mentioned here Deprecate strategy "multichain" #688
• Once we do the announcement about this, we can remove this strategy

Ah okay that makes much more sense when you put it that way. I'll refactor my changes accordingly.

PR snapshot-labs/snapshot-v1#3229 removes the pagination strategy from the UI. Technically someone can still update their space strategy setting by calling the hub api, but I feel like removing the strategy from the UI is sufficient enough. I would like to hear your thoughts.
