Of course Linux offers tons of features people like me or you might like (I'm a KDE dev), but there is also a vast amount of Linux user who for example discovered Linux by installing a VM for an uni project or have to use a POSIX environment for a programming project and then decided to stick with Linux because they liked it. There is a serious risk that people won't be tempted to try the Linux desktop anymore and instead will just use WSL. This is bad as it means less potential new contributors and enforce even more the dominance of Windows on the desktop.
