What is the optional tag for? as in what is basic use vs. what is extended use of the kernel (requiring the optional software)? Who uses the optional tag? I can imagine there used to be people with scarc= ely memory, bandwidth or computing power. But I don't think this is still the c= ase nowadays. Who else would use the tags? Thanks Manuel
