This is not strictly true. Indexing an array of such structs
will fail if the code doing it is generated by a compiler that
didn't use the exact size.
But that will indeed not to happen, as hosts are assumed to use
ladspa_descriptor() provided by the plugin.
This makes is backwards compatible, as no new field is required
in the descriptor struct.
AFAICS, binary compatibility is not compromised by an expanded
descriptor struct, as long as additional members are appended to the
struct.
