This is the best place to ask questions ;)

I don't think it's a bug. Indeed useradd does not append user to the
sudo group, but sudo is configured in a way which gives users that are
members of the "sudo" group more power, so you can just add your user to
this group (with usermod  -G sudo -a username). However (in my humble
opinion) much safer is such a sudo configuration, which forces asking
for a password, disable timeouts, etc. For example:

user    hostname=       PASSWD:/bin/su

in my opinion is much better than

user    ALL=(ALL) ALL

So you can't do "sudo -s -H" to run root's shell, but "sudo su -" will
do the trick.

And adding
Defaults        timestamp_timeout=0
is always a good practice. Please look at "man sudoers" for more details
on sudo configuration.

Of course if a user is not allowed to run particular command with sudo
it won't be allowed to run them with gksudo and any other wrappers, so
take that into consideration. To sum up: adding your user to the "sudo"
group will make things "just work", but fine tuned sudo will be safer if
you have evil cat running through your keyboard ;)

Happy hacking!
