Did he specifically call out the Twin Otter? I didn’t think they used WASM gauges. Everything was advertised as being stock to avoid this very issue.
Not so much for issues as for reasons they didn’t add something considered “standard” by forum users (who are probably mostly the minority who like more complex things). Based on the amount of things that were cut for ostensibly that reason that have since been added in, I don’t know that they fully understand the platform or its limitations and are being very conservative.
Much like the PMDG/Asobo bus-throwing contest, the only people who will ever know are the ones directly involved.
