Why do daemons only read their configuration file when they start up? Why can't they "react" to changes in that file/hot reload?

linux process configuration daemon inetd

                          I know daemons have to be sent a HUP for config changes to take effect. But I'm wondering why this is, and if it is possible to create a daemon responsive to such changes.
