What makes you think so?
variables hold complete conditional blocks. Most interested in this so that I can make sensible decisions about what to do if an image CRC is bad for example (or when to boot a different image after an upgrade).
You can use conditionals everywhere: in interactive input, in environment variables, in scripts ....
Examples, examples, examples is what I'm looking for rather than a dry explanation about hush (which I can get close to from any book that documents bash!!)
