chained are i686 arch? Is it only us(centos) or redhat's 
bugzilla should be notified.

Most likely there are dependencies that aren't available in your
current repos that are preventing the downgrade.  Perhaps its due to
the recent point release to 7.1611?

The packages installed with a 'yum downgrade' are unlikely to be
supported, so this is probably not really something that CentOS
supports.

but Centos should, right?
Being able to downgrade can save you a day or a few. I know, 
for it did save mine several times, eg. buggy samba new 
update and downgrade fixed it, etc.
We absolutely should be able to downgrade every rpm, if this 
is just a matter of an opinion(I'd fail to see any other 
reasons to not do it) then my vote goes obviously to - 
Centos/repos maintainers please make sure "yum downgrade" 
will always work.

many thank,
