That's our general forwards-compatibility guarantee: The last version of 2.6.x is the only version guaranteed to be able to read a 2.8.x database/file. In this case (but not in several others) users will be able to save their databases in another format and read it with earlier versions. I'll have to add a feature flag to prevent earlier 2.6.x versions from opening a file created with >= 2.7.3 (it's obviously too late to add it to 2.7.2).
There's an important advantage to using ISO-formatted dates in SQLite3: It allows the same date string can be used to query all three backends. That's not something that we use currently but it will be important as we convert the query system in the next development cycle. Alen has created https://bugzilla.gnome.org/show_bug.cgi?id=791848, let's move the discussion there.
