Are debugging symbols similar to Ubuntu's ddebs planned?

See https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages

The reason why I am asking is because the old style debug packages are hacky and bad. For example, the package libgl1-mesa-dri-dbg does not provide debugging symbols for /usr/lib/x86_64-linux-gnu/dri/i965_dri.so
