The issue is (as someone who used AutoCAD for nearly 30 years) that there should be a means of showing coordinates so that you don't have to continually guess BEFORE placement. It's a massive time saver and it really is MISSING.
Seeing the coordinates after the fact still requires a lot of guesswork, which anyone who is trying to put together something that requires a bit of precision will not be satisfied with, regarding the lacking feature.
Knowing it after the fact is okay, but not having it before the fact defeats the purpose of getting it right quickly.
I'm thankful I don't have to rush anything on my own end of things these days, but really the issue itself is highly annoying, to the point I just want to go off and use a different 3D modelling system (Blender, for example, which does have the ability to display X/Y/Z coordinates on the fly).
That being said, the limitation is not merely costing Autodesk business, it's costing Autodesk users (even free ones) time best spent on other tasks, and is, therefore, a significant limitation.
So... come on, coders! It's not that difficult to implement!
