@gargron Afaik most stuff isn't out of date. Just the PEAR::DB shit, but that's because it's a fundamental part of all the database queries and exchanging it to PDO or something would be way too much work.

Last time I checked composer wasn't available in Debian and I personally have no interest in forcing people to start using some random software off the web that hasn't yet made it into any repository with well-known package signatures etc.
