The local repository manager would, perhaps, click on a checkbox that says 
'freeze this package in my local repository 

Configuration would include the means by which you seed your local repository; 
yam or straight rsync for instance.  Pick some repositories (not unlike the 
baseurl you already have in yum.repos.d/random-repo.repo) to configure, then 
let it populate your local repo.  When you want to freeze a package, you (the 
local repo manager) click 'freeze' next to the package (need some depsolving 
here, since updated versions of other packages might require the ackage to be 
thawed).  Then the local yum clients use this local repo, and the frozen 
packages aren't updated until the local repo manager thaws the package and 
updates his local repo.

No, it doesn't solve time-travel issues.  But it does allow a stop point to be 
set at a particular package(s).

And that's a laudable goal.

But the whole 'maintain a local repository' mantra begs a utility to help one 
maintain a local repo.  And maybe yam can already do all that; don't know.
