That's right, we will be able to cut it down in the future. Let me explain why:

1. Enso compiler bases on GraalVM which is 400Mb (packed)[1].

2. The package contains GraalVM implementations of Python[2], R[3], and JavaScript[4] compilers, which weight 150Mb, 70Mb, and 50Mb respectivelly.

3. The package contains OpenCV library, as Enso has built-in bindings for it, which is 200Mb.

4. The rest (approx 200Mb) are core Enso libraries and tooling.

We will be able to cut it down in the future as soon as we release Enso Marketplace which would allow you to install these things on-demand.
