The current dwz.1 man page says:
The tool handles DWARF 32-bit format debugging sections of versions
2, 3 and 4 and GNU extensions on top of those, though using DWARF 4
or worst case DWARF 3 is strongly recommended.
Add documentation on dwz now handling (most of) DWARF 5 plus any limitations (on split-dwarf related forms). See also bug #24726 on some improvements to be made in the future.
