I agree with this approach, and I recommend it.
If a custom SPI isn't wanted, there are other approaches, such as
Properties files, XML, binary, etc. It all depends on what's being stored
and the amount of interoperability one expects.
Even when I use a workspace, I don't necessarily store everything in that
workspace. Sometimes it's useful to store multiple smaller parameters in
the "standard" Preferences node. Again, it depends on the nature of a
workspace, such as whether it might be shared or copied to another
platform, machine, or user.
