There are dozens of PHP frameworks inspired by rails, it's not remarkable.
Symfony (which Delicious 2.0, Yahoo! Answers, Yahoo! Bookmarks, Dailymotion v2009, etc. were built on) has a CLI too ("symfony doctrine:migrate"), and is 5+ years old.
Yahoo used a stripped down and customised version of Symfony (called ysymfony). As far as I recall they stripped out the Model part of symfony - so the entire Propel/Doctrine stuff. Answers for example, wrote their own data query/persistence.
So although you mention doctrine:migrate - Yahoo were not using it on Answers, and if Delicious, Bookmarks and Daily Motion were using the Yahoo version of symfony, neither were they.
You don't even have to "strip anything out". It's modular by nature. W3Counter (one of my sites) was built on Symfony and doesn't use Propel or Doctrine either.
