Sorry not to have checked up on this but things have been a bit turbulent as I’m sure we all can agree.
It does sound strange at first, but there’s really nothing that odd about it 
I hope I can shed some light into this.
For example, we now, quite successfully, migrated a 12 year old hobby forum running BBPress to Discourse.
That 12 years covers quite a lot of discussion, including births and deaths of terms and lingo and a surprising amount of new phenomena even in a wider context, so it’s not that odd if someone wants to dig up when was the first time some particular thing was encountered or called what it is called now 
Regardless of novelty in such functionality, I strongly believe reversing the order should be possible anyway when things are displayed in one order or another by some attribute.
