Low confidence in the platform? It's been around a while, but has also changed hands a few times and is owned by Smugmug now anyway, and I've got the impression that it is stagnant.
I have considered selfhosting myself, but it's a lot of work and features like "auto upload from my phone" and "privacy guard for pictures of my kids, but make login-free links for grandparents" are very nontrivial.
