调研方向

从链接的复现仓库开始，运行 ember test 以确认报告的行为。跟踪 @ember/debug 的导入，经过 babel-plugin-ember-modules-api-polyfill 以及 ember-cli-babel 的测试或场景套件；当 4.0 之前的应用能够导入 deprecate，且不会挂起或出现缺少导出的构建错误时，即表示完成。

描述

I was originally going to report this on the embroider repo, as I had thought it was a v2-addon issue.
But it is not!

reproduction is super easy:

// app/app.js
import { deprecate } from '@ember/debug';

console.log(deprecate);

Repro repo: https://github.com/NullVoxPopuli/repo-repro-ember-cli-babel-441
just run ember test

This was discovered while trying to add deprecate usage to a v2-addon
over in this PR

In the scenarios test suite, it seems that any interaction from a v2
addon with deprecate from @ember/debug causes the test suite to hang.

In a real app / addon ( < ember-source @ v4), a different behavior occurs (and what I was
trying to re-create in this change):

ERROR in ../../ember-resources/dist/deprecated-in-v4/use.js

According to the docs for @ember/debug,
deprecate exists, so the above code should work (I don't yet know why -- first step is a failing
test reproduction, but ran in to the test suite hanging issue.)

For [email protected]+, the above issue is not present -- and judging by
how (I happen to know that) pre 3.27, all ember apis were on the Ember
global and that embroider has no compat-adapter for @ember/debug,
my hunch is that this is actually ember-cli-bable related -- but I
wanted to open a test here, since embroider has a much better
"e2e"-style test suite than ember-cli-babel does.

Also, the stack trace shows babel-plugin-ember-modules-api-polyfill,
which is managed by ember-cli-babel.

however in writing this commit message / PR description_, I've found
that this behavior exists on a vanilla 3.25 app (new as of now).
So since the reproduction is not at all embroider or v2 addon related,
I'm going to post on ember-cli-babel
