Is it possible to use t3env from a Drizzle config file?

I'm using create-t3-app but I'd like to use Drizzle instead of Prisma. I've managed to get it working, but the one pain point I have is that I can't get t3env to validate variables in my Drizzle config file. I've tried importing it normally but I'm hit with the error SyntaxError: Cannot use import statement outside a module in env.mjs, which I find odd since it is explicitly marked as an ES module and runs fine when building the page. Full Error:

Reading config file 'F:\Projects\PROJECTNAME\drizzle.config.ts'
F:\Projects\PROJECTNAME\src\env.mjs:2
import { createEnv } from "@t3-oss/env-nextjs";
^^^^^^

This is my Drizzle config file:

import type { Config } from "drizzle-kit";
import { env } from "~/env.mjs";

export default {
  schema: "./src/server/schema.ts",
  out: "./drizzle",
  connectionString: env.DATABASE_URL,
} satisfies Config;

import type { Config } from "drizzle-kit";
import { env } from "~/env.mjs";

export default {
  schema: "./src/server/schema.ts",
  out: "./drizzle",
  connectionString: env.DATABASE_URL,
} satisfies Config;

Let me know if this is right place to post this or if a gh issue would be more appropriate

drizzle-kit is going to have esm support this week. After that it should work properly
