FWIW, if I were designing the .egg format today with 20/20 hindsight, I
would use 'package-version.egg-info' instead of 'EGG-INFO' as the metadata
directory. It would make discovery and converting to flat
(pip/legacy-style) installations easier, as you could just unzip to the
Apart from that, I'm not sure what else you'll actually gain by introducing
a new format. IIUC, what new-style metadata egg files lack can be
determined programmatically from their contents or the existing metadata
files, so there seems to be little reason not to at least consume existing
Conversely, egg files support arbitrary metadata -- which means you can
include whatever additional new-style data you want... so there seems
little reason not to simply add whatever extra metadata you want to them.
