Please have the installer apply security updates as part of the install. That way the system will be secure from first boot.

For years I interpreted the "Download updates while installing" checkbox to be intended to actually download all the updates and install all of them before finishing the install. (Instead, it does precisely what it says: downloads updates — without installing them. And it will only download updates until the install finishes — even if the install finishes before all updates have been installed.) I am not the only one to have been confused.
One reason it doesn't work that way though is because this can significantly lengthen the time needed to complete an install especially if using an original ".0" ISO for an LTS that has been out for several months or years.
I think the tradeoff may be worth it for the security updates. If not, I guess you could add yet another checkbox for "Install security updates now". And if you add that, you may want to add another one for "Install other updates now".
