Having battled (and still battling as we speak) with adding extra features to an existing simple contrib node, I think it would be a REALLY good idea to have a slightly (just a bit) more complex example than just the current lower-case one.
I.e - one with fields and properties etc
If you've been following my trials and tribulations - you'll know I'm not the person for the job but by golly , I'm a good ideas person and an excellent critic and willing to do any work needed
Not quite at the ready to be at the helping out stage yet until I've beaten my present project into submission but just putting this out there now
FTAOD I see this as a community project by the "regulars" and not for the core devs
