"Sure, but the cost of schema maintenance is grossly overstated by those who simply aren't familiar with the tooling to do so." Scale ruins everything. Most SQL databases are pretty terrible at schema maintenance at scale (i.e. hundreds of MySQL shards). This (among other ways that scale ruins the RDBMS) is what led to NoSQL in the first place at the largest of web properties. Sure, joe average startup probably doesn't have the same problems. But that's marketing.... The relational model and SQL have been beaten up for decades by those who prefer to remain closer to the metal.
