Remove addToStore variant as requested by FIXME

The idea is it's always more flexible to consumer a `Source` than a plain string, and it might even reduce memory consumption. I also looked at `addToStoreFromDump` with its `// FIXME: remove?`, but the worked needed for that is far more up for interpretation, so I punted for now.
