When I was handling releng stuff, I liked to use the amount of days it would take to realistically fix things as a hubristic.  If it was going to take more than a day or two then it was probably worth it.  I also would make sure there has been some prep work, like attempted rebuilds in a local mock to find errors before we spend resources in the build system.

Your task of bumping libpng does seem like a reasonable use of a topic tag.  Although I'm not releng for Fedora anymore, I would recommend spending some time with mock testing the rebuilds to find errors before we create a divergent line of development.  The longer the topic-tag exists, the more risk you have of conflicting changes going on in rawhide vs the changes you're making in the topic-tag that will have to be reconciled.  The topic-tag should be used to get the work done, not explore what work might be necessary.
