Probably less extra work right now than ten or twenty years ago. For one, OpenBSD (and others?) did this a while ago. If it breaks software when Debian does it, it was probably mostly broken. For another, most people are using 64-bit os and 64-bit userland. These have been running 64-bit time_t forever (or at least a long time), so it's no change there. Also, someone upthread said no change for i386 in Trixie... I don't follow Debian to know when they're planning to stop i386 releases in general, but it might not be that far away?
