No, a hose split is not reasonable, neither is a blow off. To make sure it doesn't happen you use hose clamps and forget about it. That's what I meant by "good design".
What has happened historically, is that a brass barb in an Aluminium top would corrode, and break a seal: just don't do it. Hose split has happened once, when the water was allowed to get so hot, that it melted the tubing, so don't allow that to happen either, that's all. The same heat can melt a plastic top, and cause an o-ring failure: I've seen that twice. They were the result of either a lack of OCP, or OCP failure.
