Synchronized viewport behaviour

I saw that there’s a development for syncronizing viewports across tabs (

Unbeknownst to this I made a proposal to synchronize viewports in the same window/tab.

It was brought to my attention that I should maybe propose my design in the development. Since I don’t really want to spam it there (and even can’t, I think) I though I’d ask here: Could this be implemented as well - resp. could the development diff cover this functionality already?
