Root route imports are always bundled for edge

[DuncanLHS]

As a result of issues with unsupported modules similar to #94 and #104 (in my case the problem is tailwind-merge) I've been trying to avoid edge and have everything run in node for the time being. However, as soon as I start adding UI to my root file I get the unsupported module errors back again due to the tailwind-merge module.

It looks like everything in root.tsx is being bundled for the edge runtime. adding export const config = { runtime: "nodejs" } to root.tsx has no impact and is ignored.

Is this intended default behaviour? How to get around it?

The root layout is indeed included for all leaf routes. If you have some common layout which is using modules that are not supported on Edge runtime, consider defining a pathless layout which has export const config = { runtime: "nodejs" } and then you could nest any routes which use that layout underneath that pathless layout.
