Yes, there are gaps in that list, i.e. calls that are currently not shown as doing anything so you could grab one of those and, as it is a Wiki, edit it to say what you're using the call for. That is probably a better situation than existed back in the day.
The only thing to be aware of is that, with OSWORD, there is a limit to the set of calls where the tube software, both host end and the clients in second processor boot ROMs, knows (from a built-in table) how many bytes should be transferred. To add new OSWORDs you should adopt the convention where the control block contains this information, i.e. how many bytes to transfer in each direction.
