Any virtualization solution has the complexity of the sum of the environments being run simultaneously, the virtualization solution, and the surface where all 3 interact. Furthermore the guest solution inherently deals with the system at a higher level wherein you are stuck with how the host handles lower level aspects. Such a system is simultaneously worse and more complicated as a necessary price for running both native windows applications and linux ones. In most cases you would be better off just running Windows or running actual Linux. For example my Linux system has a ZFS root filesystem which provides a lot of interesting features including the ability to boot a prior version of my install at startup, along with 37 other useful things. Running a linux VM with that feature wouldn't magically port this functionality to the rest of the system. My Linux system is vastly less likely to fall victim to a cryptolocker or other malware situation but running a vm under my Windows desktop wouldn't deliver this benefit. My Linux system handles virtual desktops per monitor making it easy to swap one monitor at a time to a different workspace or all together if I please. Again neither running an app via a compatibility layer nor a fullscreen VM would provide this functionality. WSL is Linux light without most of the interesting features and able to be withdrawn any given year by Microsoft. Worse it could be extended in ways that depend on windows features in a classic Microsoft move.
