Yeah, I think so. There is some overhead to doing the scaffolding (invoking multiple drawing tools, erasing stuff later, etc...) but if you are already spending some time planning things then this overhead is not a problem.

But if you want something quick, for instance just getting a cylinder drawn at the correct orientation at an approximate height or lateral offset location for a type of quick visualization sketch, then clines keeps things moving along really speedily for that type of a thing because placing just one or two clines is super quick and there is no erase time. Like it might take you only 2 seconds to place the quick cline temporary "scaffolding" in place, but maybe something like 10 seconds to place regular geometry scaffolding, especially because for regular geometry scaffolding you have to trigger multiple commands and also possibly move stuff around a bit since you don't have the implicit extensions that clines have built in.

10 seconds versus 2 seconds is not a big deal if you've already spent a few minutes planning stuff out. But if you want to just draw and sketch stuff really quickly, it does become more significant because just a few more seconds starts to take away the rapid "drawing" type feeling...
