Question about socket ext. file descriptors

At present, the sockets extension uses integers as file descriptors (e.g. socket() return value). At first I thought maybe they should have been resources until I tried writing some socket code, when I realized that it's easier under many circumstances for them to be ints. Is this going to be behaviour that can be relied upon?
