glebfm@ and legion@ are busy now with this.
They could give most details about this process.
The first thing to do on this way was to rebase many ALT's features
onto rpm(-install)-4.13. (Not yet features relevant for rpm-build.)

Apart from the first important step (rebasing ALT's rpm-install) which has
been done and is ready for testing, there are things would hold us back
from putting the new version into ALT Sisyphus:
those packages which use librpm and/or access RPM's db will have to be
adapted for the new version. (The first one, of course, is APT; then,
there are some Perl bindings actively used by the tools for automatic
package analysis, modification, submission; perhaps, some more, I don't
know the list of things that hold this back well, but other involved
people could tell you more.)

As said, there are a few ALT-specific nice, important and
non-trivial features in RPM, which would always require maintaining a
separate fork unless they are taken up by another RPM project, say, the
rpm-4.13 project. Then the forces could be joined.
One of these features is the support for set-versions (the <= relation,
which is used to constrain Requires/Provides, which would behave not like
a linear order, but like inclusion of sets), developed by at@ in the past.
Now, he has announced that he is developing an enhanced varaint of this
feature and could tell the details about the current developments to those
who are interested.
support for prototypes/signatures similar to C++ mangling, but for C).
at@ has pointed to his new work at https://github.com/svpv/rpmss --
https://lists.altlinux.org/pipermail/devel/2016-August/201701.html . At
the same time, at@ shared his belief that if there is some code in ALT's
RPM which was once written and works correctly since then, there will be
no need to put efforts into maintaining it; and so, he sees no
justification in the complex work of rebasing onto rpm-4.13 because this
would not save us any future efforts in maintaining ALT's RPM compared to
the current situation. (Zero efforts if the current code of RPM works
