Ah I see. The whole tree would have to be scanned for SHA256H references of a certain SHA256 key on `get` and tree-modifying commands like `checkout`.
With the existing backends that doesn't need to happen since the key existing in the local repo implies that it is reachable via the symlinks in the checkout.
Trickier than I had anticipated, thank you for your insights!
Maybe the extension aliases of a key could be recorded and simply applied in every repo a key exists in. This might require another lookup on get (though it could perhaps be done in the same lookup) but, since it'd require a lookup of a key anyways under SHA256E because they're entirely separate, we wouldn't lose on performance either.
The only problem would be propagating new aliases on `sync`...
