I surely hope so, given that these make it possible to do things with Wine which are difficult if not impossible with a real Windows installation without having to do silly things with VMs or containers. As an example I use Wine to run Sketchup (2016, off-line) on Linux. After 30 days the thing times out and wants me to buy a license which is no longer available given that Sketchup has gone with the times and now does cloudy things. Since I just want to run the thing off-line without any external interference I prefer the 2016 version over newer incarnations. On Windows I'd have to try to eradicate every last trace of Sketchup from the registry and any other location used to determine whether this is the first time the program has been installed. On Linux the solution is simple, just wipe $WINEPREFIX and re-install (an automated process) to the same location. A simple script does the job, sketchup -r and I'm set.

By the way, $WINEPREFIX can also be used to make sure you don't wreck your entire Wine setup with a single typo. Just make sure all your serious use of Wine is done with a specific, non-default prefix and you're set.
