That does not mean that you can't get away with not using that approach occasionally. Using that approach, however for a reliable solution is dangerous.
Right, and the whole point of Arduino is to simplfy things for beginners, no direct port manipulation for example, so lets stick to the basics on the hardware side when newbies are asking if a resistor is required for an LED.
Now I know what the ugly stepchild feels like. Lets hide him in the closet when company comes to visit. sigh.
So, the next time someone specifically asks:
"LEDs without the use of current limiting resistors"
And gives a very specific example, we are supposed to tell them that its impossible to do that, and they should never think such dangerous thoughts?You sir are free to do whatever you wish to your arduino on your projects. However if you post information to people asking for help, some people will probably continue to warn against poor advice that sometimes get posted around here.
So unless your looking for some kind of validation for your methods and advice I don't see where you have a valid complaint to share with us.

Im not looking for validation here buddy. Answer the question, what are you suppose to tell someone that asks a valid question, and provides a documented example.
I think the best answer to the question is, yes, that is possible under certain circumstances.
It may be that they need the display to fit in a tiny space, but it only needs to work for 3 days and never used again.
Also, I cant take credit for the design, I just found it on the interwebs, and built one. I can only take credit for experimenting with it, talking to people about it.
