It's not intentional. We actually held back more complicated features for years to make it easy to self-host (e.g. only used Postgres and Redis as data stores for a long time).

The complication really just comes from the new capabilities we've added, and the dependencies that come with that. I suppose also our sophistication in hosting the platform has evolved (as the scale has increased), and so the tooling we use to manage it has become more complicated.
