Manifest: should JSON output for devices be a dict or an array?

[lpascal-ledger]

Currently, when outputing the devices:

$ ledger-manifest ledger_app.toml  -od
devices:
0. stax
1. nanos+
2. nanos
3. nanox

$ ledger-manifest ledger_app.toml -j -od
{"devices": ["nanos+", "stax", "nanox", "nanos"]}

... which prevents to directly use ledger-manifest in shell scripts (including GitHub actions). One needs to:

compatible_devices="$(ledger-manifest --output-devices "$APP_MANIFEST" -j | jq -rc '.devices')";

What should be the proper behavior?
