That makes no sense.
You might want to look at the experiments to do something like that from Tom de Vries: https://sourceware.org/pipermail/dwz/2020q1/000579.html https://sourceware.org/pipermail/dwz/2020q1/000568.html > It is all about engineering effort.

Hacking on dwz and supporting partial units and DWARF supplemential files in debugger like tools isn't trivial. But it is IMHO also not such a big effort that we have to drop everything else. Lets see if we can work together on this.
