Variants that only add a runtime dependency aren't a great idea. A
variant like this doesn't actually change anything about the port
itself. The installed files are exactly the same as they would be
without the variant, which means you unnecessarily miss out on using an
archive.

In some other package managers this would be in 'suggests' rather than
being a dependency. Perhaps some notes mentioning that the port installs
a completion file could serve a similar purpose?
