I really prefer to hide as much as possible from day 1. Maybe the structure can be split to two? Currently IIO has a (painful and long) conversion from open to opaque. Taking this into account I really don't won't to repeat this design mistake. But it's all up to the maintainers, of course. Just my deep worries about this... while the idea, as I said, I fully support. -- With Best Regards, Andy Shevchenko
