so much this ?Actually I hope not!
1/5 people will try to do crazy thing I guess!
All the others will use it with AIO or small custom loop.

I love the the combination of simplicity, compatibility and still ease of use at this small scale.
For everything else you can go into bench-mode, as @fabio has shown many times
