Parameter objects are very practical and have ample use scenarios, both high-level and relatively low-level.
I would be interested in hearing about these use cases. In particular, parameters (unlike fluid/dynamic variables) are first-class: they can be stored in local variables or data structures. If you have any use cases of this kind, I very much would like to know.
