Is this a dnf/koschei issue or with the above conditional requires?  Are 
these even allowed yet in Fedora?

I assume koschei (and friends).

I also assumed so, since these rich deps are being used for langpacks 
already

If that's not the case, I can certainly revert the changes

My understanding is that they are certainly allowed; however, I don't
think anyone has really done a lot with them, especially with Koschei.

DNF can totally process conditional dependencies as libsolv in Fedora
is compiled with support for it. I'm not sure why Koschei isn't
handling it well.

Maybe because Koschei builds using mock (?) and mock by default still use yum (but
rawhide) and yum cannot handle those
new dependencies.

First, Koschei uses Koji for building, which uses DNF for tag f25:

$ koji taginfo f25
[...]
Tag options:
  mock.package_manager : 'dnf'
[...]

Secondly, the mentioned error comes directly from hawkey library and is
not related to mock/Koji at all.

Well, fedora koji builds appear to be working fine, so I'm guessing something
is out of date on koschei's dep check.

As I understand it, koschei uses some local code for doing the dep check.
I've filed https://github.com/msimacek/koschei/issues/82

Unsurprisingly I guess, just received a bug filed today about how yum 
doesn't work with the rich dependencies either:

yum-compatible rich dependencies

So as a followup , here's my findings:

*  There are quite a few tools in fedora that still utilize yum code for 
various things (including mash for composing updates), so knowingly making 
things incompatible at this point is probably not an option.

* yum obviously supports 'Requires:' tag, and recently grew support for 
'Recommends:', so one cannot safely use Rich dependencies in combination 
with either

* yum does not support Supplements/Enhances, so using Rich dependencies with 
these appears safe.  It is my understanding that recent langpacks support 
for f24 is utilizing the Supplements tag

For dependency resolution Koschei uses the same libraries as DNF,
but it looks like DNF doesn't support rich dependencies yet:

# alias dnf
dnf='dnf -q -y --repofrompath
rawhide,https://kojipkgs.fedoraproject.org/repos/f25-build/latest/x86_64/ --disablerepo
\* --enablerepo rawhide'

# dnf repoquery qt-x11
qt-x11-1:4.8.7-11.fc25.x86_64

# dnf repoquery --requires qt-x11 | grep sni-qt
sni-qt(x86-64) IF plasma-workspace

# dnf repoquery --whatprovides '(sni-qt(x86-64) if plasma-workspace)'
*** Error in `/usr/bin/python3': double free or corruption (!prev):
0x00005607e0b15710 ***
[...]
Aborted (core dumped)

# dnf install '(sni-qt(x86-64) if plasma-workspace)'
Error: Unable to find a match.

Tested in rawhide using:
dnf-1.1.7-2.fc25.noarch
hawkey-0.6.2-4.fc24.x86_64
libsolv-0.6.19-2.fc25.x86_64
