Are you aware that there is nothing to stop an application to use
a larger FD_SETSIZE if it so desires? Just #define FD_SETSIZE xxx

No need to generate a new kernel or something.
IMHO that's flexible enough to get the best of both worlds (i.e. space
savings in small applications vs. support for many connections in large
