include_unresolvable flag are not working

[intrd]

The user_guide says:

include_unresolvable | When set to true, causes DNS names that did not resolve to be printed

So, I'm trying to set it at config.ini:

include_unresolvable = true

Running it w/ the command:

$ amass --version
v3.16.0
$ amass enum -config /path/config.ini -v -src -max-dns-queries 50 -dir DB/test/ -d testdomain.com -o out.txt

And.. it never prints the unresolvable subdomains.. neither stores in DB/test/amass.json, only resolved are printed/stored.

The only way I've found to print/store the unresolvable subdomains are using the -passive mode.

I'm missing something? thank you guys.

Update: Also tried on v3.17.0, same bug.

I'll make sure the flag is removed from the documentation, since the feature was removed a long time ago due to the performance impact. Perhaps it could be reconsidered in v4.0
