What Devs are building to enable zaps from wallets that are too small to be economical on the base layer, is applicable to the future of Bitcoin. These micro transactions are the marginal case for Bitcoin that will continue to grow as Bitcoin adoption continues. Minimising trust and maximising access and privacy is essential. Proof of reserves, open source code, no KYC etc. 

These are all compromises from securing your own keys. We need to make sure that as the base layer becomes congested that  controlling your own Bitcoin in a permissionless way continues to be the highest priority.
