Currently we're using createIdResolver from vite to create module resolvers that we use in the module fallback service callback.

We should explore if we could instead use a separate third party solution (like import-meta-resolve, enhanced-resolve, resolve, etc...).

Why would that be beneficial?

• The vite team exposed the createIdResolver utility especially for us, but this is not a utility that they would like to have to expose and maintain (discussion)
• We could reuse our module resolution implementation in vitest-pool-workers whilst it still needs to use vite@5 (PS: this would be pretty valuable in the short/middle term, not at all in the long term as vitest-pool-workers should ideally just reuse our vite environment solution under the hood)
• Our module fallback solution could become fairly generic, we could even externalize it in its own package and it could be used in non-vite projects (although I am not sure if/what use cases for this there are)
