This is not about proprietary development, all ALT rpm features are
available in git repo at git.alt [1] [2].

It would be better to consolidate efforts but currently ALT rpm is a
fork with more than a decade-long history and a lot of good features
implemented such as autogenerated dependency for various interpreted
languages, set-versions, checks and a lot of other enhancements, and we
just can't drop these. Still we tried to port ours changes to new at
that time rpm 4.13 to keep our rpm closer to upstream (for now it
provides rpm(8) and some other, but no rpm-build).

And what about features ALT already has? They are integrated to ALT
package ecosystem with repositories with thousands of packages which
should be able to be installed and handled by package manager. And what
about the features like set-versions, which you don't want to integrate

We asked for 100 rpm tags with a big reserve.

At the moment we want to use RPMTAG_AUTOINSTALLED in rpm db that helps
apt to determine what package was installed automatically as a
dependency of manually installed packages.

Second tag we want to use is RPMTAG_IDENTITY which determine a
characteristic of package build and is represented hash of significant
tags (in opposite to RPMTAG_SHA1HEADER, that is a hash of all package
