It appears that `-prune` is ignored during import (`-reindex`, or `-loadblock`).


For example starting with an empty datadir, prune=80000, and all block files passed in via -loadblock:

```
...

```

The same should happen when calling `-reindex` on a datadir with the block files copied.

So prune only works with IBD from the network?
