This isn’t recent. This has been an ongoing thing for at least 20 years (if not longer; that’s just the earliest I remember having this convo). Yes, it cleans the wound by killing things but it also fucks up the healthy tissue around the wound (see other comments for a more scientific explanation). Having some in a medical kit is useful for other activities such as diluting with water for an ear rinse, diluting with water for various mouth stuff (rinse not swallow), and some skin treatments (again, diluting first).

If you’re on a Windows box, the apps you’re calling out are assuming some level of FHS or XDG compatibility, neither of which are Windows things.

If you’re on a mac, macOS uses its own thing but can play well with dotdirs. However, you’ll find a mix of assuming XDG and weird macOS storage locations depending on how the tool determines storage location priority.

If you’re on Linux, there are too many standards.
