There is a very scary thing about digital art where platforms at any time can remove things or silently release a new version. It makes me uncomfortable in the same way as when newspapers online make updates to their articles with no transparent revision history of what was changed and when.
The technology just makes it easier though. The Foundations have been trying to erase the original Colin Young version of Build me up Buttercup that I love in favor of Clem Curtis rerecordings since long before Internet was a thing, as an example.
So just aggressively back up versions you like as they are released. If you don't save it for yourself, you can't guarantee it won't eventually disappear.
