Yes it’s a big problem, in comparison to CAD. In the final output, I often draw thicker lines over edges that need emphasis and have to give up the hierarchy of graphics that I use in most drawings.
I often do not do this until working drawings are almost complete, because it does not update with changes. And I have to put up with others looking at drafts in confusion because of the lack of definition.
“Fog” helps and is nice in a way, but control is poor and there seems to be no desire to change that over the years
