Implementing WebGPU allows you to make use of GPU resources on the server (from rendering to more compute focused) Localstorage is admittedly a bit niche, but works well as a way to bypass the need to get generic read/write permissions for the filesystem for a config file. (Deno implements a permission model similar to the web where you start with nothing and must request / have pre-granted access to resources like files/network/env/subprocess, and this access can be granular to specific files/directories/host+port combos)
