I was talking about the application itself and not the package format.

But yes, in Debian packages it has "never" been absolutely accurate IIRC.
I imagine that it would be possible to find workaround by using some
some internal representation of the file types and numbers in the
package and a guessing algorithm for the used file space.

But what for? Packages can even create temporary stuff during
installation which you cannot predict well, or even persistent data
(index caches etc.). So this information in the packages is not more
than a coarse grained estimation of the required disk space.
