The updates are much needed and welcome. I’m reasonably savvy, but not a developer, the level is about right for me. I doubt it is worth going lower as unsophisticated or inexperienced web users are unlikely to grasp the nuances of an Indieweb - at least for now.

One area that could use more work is integrating with WordPress themes. These are far more complex than they were five years ago, use more php files which make it harder to find and deal with various hooks. This is probably easy for developers, but a struggle for even advanced non-coders.
