I'm not clear on your understanding of how Parchive works and what it is
for. It's merely for verifying the integrity of data, and repairing said
data if there is corruption. It is not an archive file format ala tar, zip,
et alii.

As for longevity, Parchive is nothing more than an application of
Reed-Solomon coding. The algorithm isn't new, and it is used pretty much
everywhere[1].
