I actually think that's a bad idea, storing video is expensive and will quickly make hosting instances unsustainable. This kind of feature creep is what made Reddit an unprofitable black hole, and should be avoided.
i mean that's a fantastic point, however community video content to me is extremely valuable and im struggling to fully switch to lemmy because of this
You can easily store the video somewhere else and share it here. Lemmy is primarily a link aggregation platform and more walled gardens is the last thing the internet needs anyway.
The alternative is no Lemmy because copying every single video to every single instance would bankrupt most of them.
