As with "in-place upgrades,"[1] the compelling use case is being short
on disk space. For somebody with a multi-TB (or whatever figure
sounds big this week) PostgreSQL database, it may be impossible to get
space for twice or more that. Giving people the option to stream
COPYs through a pipe would alleviate a lot of pain.

[1] A feature people seem to think we don't need, although convincing
cases have been made for it.
