Description

Not many people know what to do with the proj_id argument of AreaDefinition. Maybe we should just deprecate/remove it.

My main argument against deprecating it completely is that I think a projection ID is something used in Well Known Text (WKT) specifications of coordinate systems. Any other objections?

Research direction

Start by locating AreaDefinition and searching the repository for proj_id references, including callers and tests. Read how projection information and WKT coordinate-system specifications are handled, then determine whether the intended outcome is deprecation or removal. Done requires a documented decision and corresponding updates across the affected API and tests.
