Why load_raster and not load_url?

[vincentsarago]

well I originally though that load_raster would be more explicit as for load_collection but totally open to naming if we ever implement this

It's not just naming, there are predefined processes with schema for the usecase, which is load_url (and potentially load_uploaded_files). I understand it's hard to navigate the processes due to the sheer amount :) if everyone uses the same processes more or less, you have portable processes that can ideally run everywhere.
