At some point a clear-text password will show up, but that doesn't require
said password to always be in clear-text.

Think of a remote system that provides said passwords and authenticates
the system asking for said password using some private/public key
authentication that can be easily revoked (on machine comprise and such).
Then u will get a closer view to why it'd be nice to have keys go through
a API so that they can be gotten from other sources (to enable such a
system to work). The plain-text case is an API, but it restricts it to the
simplest one (only plain-text files), other companies (cough cough, yahoo)
have different systems.
