I feel like WebDAV will have staying power for a simple reason: it’s easy to understand and implement. My company has a cloud platform for people to share files and I am working on a feature to allow it to work as a drive through WebDAV. We may support other protocols later on but WebDAV made the most sense to start off with because we already have all the infrastructure we need to deliver files over HTTP. The amount of additional complexity to support WebDAV was near-zero and the amount to support other protocols would be a lot more.
