Less is safer: How Obsidian reduces the risk of supply chain attacks

This is one way to look at it, but ignores the fact that most users use third party community plugins.

Obsidian has a truly terrible security model for plugins. As I realized while building my own, Obsidian plugins have full, unrestricted access to all files in the vault.

Obsidian could've instead opted to be more 'batteries-included', at the cost of more development effort, but instead leaves this to the community, which in turn increases the attack surface significantly.

Or it could have a browser extension like manifest that declares all permissions used by the plugin, where attempting to access a permission that's not granted gets blocked.

Both of these approaches would've led to more real security to end users than "we have few third party dependencies".

Don’t most plugin models work this way? Does VSCode, Vim, Emacs, and friends do anything to segregate content? Gaming is the only area where I expect plugins have limited permissions.
