Yes, that’s totally the plan: We already have https://map.taler-ops.ch/ (buywith.git) and the exchange has the “SHOPPTING_URL” feature which (for CHF) links to that map. What is missing is support in the Wallet GUIs to expose the link from the action menu.
What it could be interesting is the proposal is about bringing a integrated solution with the walelt so the user can download information from the payment service provider (aka the exchange) for which the shop did the KYC/KYB process and use that information to navigate an offline map.
That could be a future verison of our planned maps
