Over the years we've several times discussed possible reasons for this and how to help. I personally think it's two things: 1. lack of toolchain and fs support. The fact that we cannot to this day enable ping using capabilities by default because of cpio, tar and non-xattr filesystems is disheartening. 2. It's hard for users and applications to know what caps they need. yes the API is a bear to use, but we can hide that behind fancier libraries. But using capabilities requires too much in-depth knowledge of precisely what caps you might need for whatever operations library may now do when you asked for something.
