We would like to do that as well, but sometimes snapshotting is not enough. We have had major security fixes in the past that could only be fixed via reindexing. There are different reasons to reindex. Getting a node up for the first time is the most common and makes sense to load from a snapshot. But in the case of a security vulnerability or a chain halt that requires a reindex to fix, we may not be able to wait a longer time to reindex. We realize that there is not a "one size fits all" solution, which is why we are looking at the hybrid approach and are interested in snapshotting.
