Rated 5 out of 5 stars

As everyone expected, UnMHT is becoming deprecated. In the meantime, it's still an excellent addon. Its practical successor is probably Save Page WE. Benchmarks against Save Page WE show that UnMHT still has some (occasionally very major) advantages in filesize due to how it groups up multiple references to single resources.

SPWE has some technical advantages in its format, handling of corner cases, and overall structure. Maybe in the future, the gap in filesize between the two addons will be closed.
