Are there plans (or at least, sufficient interest) to expand the
current std_srvs package with more services? It currently only
supports an "Empty" service. I'm building some interfaces, and I end
up using several services over and over, such as basic
accessors/mutators:

* SetBool / GetBool
* SetString / GetString
* SetFloat / GetFloat
* Increment
* Decrement

etc

I can always define them in my own package, but having them in a
central place will make it easier to write interfaces that are
compatible with each other.
