I see discussion about it in 2003, so I guess it's been there right from 1.0.0.

Using it for author date sounds sensible.

Hmm, good question. Maybe it should be an option, though I hope it would be enabled by default (since the feature would be more metadata-preserving, which is a good thing), with an option to disable it to allow backwards compatibility with people running an older version of git. That's my opinion anyway, and I realise my opinion is not necessarily well-informed regarding all considerations.
Note, I'm unclear as to whether Subversion is willing to store timezone information in svn:original-date. But I guess having git author date correspond to svn:original-date is an improvement for preserving more metadata, even if the timezone is lost in the process.
