const stores: Blockstore[] = [new MyBlockstore()]

i was expecting this to throw an error, because MyBlockstore uses an override for a method that ultimately makes it not compatible with code expecting a Blockstore

[woeful remnant]

methods are intentionally unsafely bivariant in their parameter types. if Basestore used property syntax instead of method syntax to define put then what you wrote would in fact be an error

looks like put is defined here: https://github.com/ipfs/js-stores/blob/1c51514c4af49b022740354c6e0d3d2555d6406d/packages/interface-store/src/index.ts#L59
