This is not about personal taste. This is about violating well-established best practices that have very good reasons to exist.
Running custom scripts as root, and especially adding custom cronjobs as root, should only be done if absolutely required for the tool to perform its task at all, e.g. for tools like logrotate.
Everything else is a violation of trust, and thus a no-go for package maintainers.
If a user wants daily updates, they configure the APT or Synaptic accordingly. It is the decision of the user, preferably for the whole system, at a time convenient for them. This is certainly not the decision of a single package maintainer.
Keep in mind that many people choose a Free Software distribution like Debian because they developed an aversion to uninvited extra code running on their machine. Why? Because this is what was forced on them by their old proprietary operating system.
