@Zanna I have updated my question with text stating what was implemented, so if you like, you can tag it with status-completed.

"it would continue to be used for both zooming in and out, and the particular software application" How about splitting up the zoom into something like built-in-zoom (or desktop-zoom) and magnifier? That would also reduce the risk of incorrect tagging. I'm not entirely convinced that adding guidance to the tag wiki excerpt will be sufficient.

I don't know on how many meta sites you posted this question (here, Unix & Linux SE, Superuser SE) but please check Why can I flag my own question/answer? and Flag and close my own question, both on Meta SE.
