Hey, I'd like to comment your edit. Under usual circumstances, I'd agree with you – typically, we don't know when exactly a project would end. I wouldn't have added the end date in the infobox. But the Charts group is tasked with a specific job, and there is an official plan that we wrap up in December. We'd like to make it clear for everyone interested. After that, all staffers involved get back to their regular teams in their previous capacities. Sure, maybe later the leadership would change their minds, but for now, we're officially wrapping up in December, which is different from the usual "we'd like to wrap up in December". For this reason I'd prefer to keep the end date in the infobox. What do you think?

You should say those words (or some variant of them) somewhere on the project page then. Just having it in the infobox doesn't convey the point very clearly, as you can see from the fact that I missed it and interpreted that as a usual idealistic timeframe that I've repeatedly seen not be met.
This situation is so rare that the template didn't properly support future dates and put the page in the redlinked Category:WMF Projects 2024q4, which brought it to my attention as I monitor redlinked categories here. I'm working on fixing the template now, though.
