To be clear, Congress does not even have to delegate authority with a great degree of specificity. If you read the Communications Act of 1934, for example, it has broad provisions that expressly give great discretion to the FCC to decide matters of policy. Chevron doesn’t affect that.
Where Chevron comes into play is usually where Congress was pretty specific, because the statute embodies some sort of legislative compromise. In those cases, Chevron means that agencies can easily undo (in either direction) the legislative compromise Congress created.
