I note that the mpox dataset has "Enabled by data from GenBank." but measles does not — do we consistently give attribution like this? (Seems nice.)

Looks good to me. Please merge whenever you'd like.

Good spot, indeed it's good practice to include provenance in a structured way! This is done in auspice_config.json through a top-level field:

  "data_provenance": [
    {
      "name": "GenBank",
      "url": "https://www.ncbi.nlm.nih.gov/genbank/"
    }
  ],

Ah I see it's already done in https://github.com/nextstrain/measles/pull/39 🎉
