My current understanding is that the script that I made is changing the dynDNS logic that it currently implemented in Cloudron (batching DNS records to update in a single call vs one call per DNS record).
Without checking further, I believe that Cloudron's logic is the same for all DNS providers, which make it difficult to change or make exception for a single one like deSEC and therefore to implement.
However, this is only an hypothesis for now. It would need confirmation from a Cloudron member of staff I suppose.
