Personally I suspect that modern systems aren't as memory/disc
constrained as those when busybox was first written.
So additional code in a paged executable doesn't matter as much.
Very small systems are actually unlikely to nslookup at all.
This also applies to some of the other applets.
The defaults could include all the 'expected' options that only
increase the code size by a few hundred bytes.
Indeed all the relevant options could be hidden behind a big
'optimise applets for size' option.
