If you were aware of the fact that helix didn’t have it then a uservoice could of been put in way sooner (back when the death date for kraken was announced). We are in full “closing the gate after the horse has bolted” now.
A solution might be to store the VideoID references in your database, and then jsut add new videos as they appear.
Sure this doesn’t account for deletions.
However:

Talks about the retention of VOD’s, which, ignoring Grandfathered parters or other special agreements, is a maximum of 60 days. So if a streamer streams twice a day they are at most going to have 120 Vidoes on the service. Assuming they don’t make any highlights, and then videos will auto delete from Twitch.
Then everything else is going to be highlights. So is a raw video count actually worth retaining?
So “videos” isn’t as useful as differentiating between VOD"s, highlights and clips. A raw total is not as useful to end users as I thinkit could be in my opinion.
