It's in the 'default_doc' split function. But yes, it's not explicitly
documented.

This would add -dbg packages for everything in the entire index, not
just for the packages which are already installed.

Also the install_if works so that if you have 'docs' installed and you
do 'apk add foo' you will automatically get 'foo-doc' too if it exists.
Basically "apk add docs" means that I want to have docs on all packages
installed on system now, or any time in the future.

"apk del foo" would also remove the docs package with the 'docs' meta.
"apk add *-docs" would add dependency in 'world' and require explcit
removal of the docs too.

The point of the install_if / docs packages is to be more dynamic and
follow the installation status of the main package.

But, it does exist for add and delete too. I use regularly "apk del
*-dev". However, the use case is different than from the 'docs'
metapackage and install_if.
