I wonder if being able to update albums has been a good thing. It may encourage people to release "MVP"s because they can always improve them later. It doesn't quite fit because reviewers will review the first version.

For me personally, it has been a negative, because I really loved Tame Impala's Borderline, which was switcheroo'd with a song I don't feel for when the album came out. They even took out the single version from Spotify and YouTube (the official channel), so we're stuck with the album version. A comment from unofficial YouTube version sums it up:

"I understand him wanting to make a version with the vision he originally intended for the song but the fact that he removed the other version when it already was presented and existed to other is what is infuriating and upsetting. The single version clearly held a special place in people's hearts and to lose that is hard to swallow."

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.

Just save everything you like locally. I still do that for most stuff.
