Thanks for the kind words! You're right about the offline-first benefits - that's definitely part of what will eventually be Hologram's local-first philosophy and it's on the roadmap (https://hologram.page/docs/roadmap).
I needed to get the performance to a usable level in v0.5.0 because the previous iteration was quite slow, and I was concerned about getting bad press early on (there was actually a previous HN discussion about Hologram's performance issues). The slowness also prevented implementing latency-sensitive features like the real-time pointer/mouse events you see in the SVG drawing demo - which are really Hologram's main use case. It's already blazing fast now, though I haven't squeezed max performance yet - there's still room for improvement.
There are still some high-priority features that need to be implemented first before tackling the local-first capabilities. The CRDT implementation in this release is part of the foundation for those distributed/sync features, but there's more foundational work needed.
