eslint-plugin-import-x has eslint-import-resolver-node as a dependency. When no resolver is specified in the eslint config, the eslint-import-resolver-node will be used. However, eslint-import-resolver-node doesn't support exports and imports from package.json and @ljharb simply refuses doesn't have time to implement this feature and even locks the feature request issue, see import-js/eslint-plugin-import#1810.

So our plan is to abandon the eslint-import-resolver-node. We will be building a new eslint import resolver upon @dual-bundle/import-meta-resolve enhanced-resolve. We will ship it with eslint-plugin-import-x and it will be an interface v3-only resolver.

In the next major version of eslint-plugin-import-x, we will remove eslint-import-resolver-node in favor of our own default resolver.
