Importing paginateDescribeInstanceTypes breaks tree-shaking

[ZauberNerd]

Describe the bug

Using the "bare-bones client" imports I usually get small-ish bundles ~230kb with esbuild + --minify.
However when I import paginateDescribeInstanceTypes the whole bundle blows up to 2.1mb (minified).

Your environment

SDK version number

@aws-sdk/[email protected]

Is the issue in the browser/Node.js/ReactNative?

Details of the browser/Node.js/ReactNative version

N/A as the problem happens during bundling

Steps to reproduce

import {
  EC2Client,
  DescribeInstanceTypesCommand,
  paginateDescribeInstanceTypes,
} from "@aws-sdk/client-ec2";

console.log({ EC2Client, DescribeInstanceTypesCommand, paginateDescribeInstanceTypes });

Switch between DescribeInstanceTypesCommand and paginateDescribeInstanceTypes in the above code snippet and bundling it via:

esbuild --bundle *.ts --outdir=dist --metafile=dist/metafile.json --sourcemap --minify

Observed behavior

Importing paginateDescribeInstanceTypes blows up the bundle and includes everything (same size as when importing:

import { EC2 } from "@aws-sdk/client-ec2";
console.log(EC2);

Expected behavior

As with other Describe* and paginate* methods, importing them should not result in bundling the entire EC2 library.

note for fix: the paginators should not attempt to use the aggregated client, since that static import blows up tree-shaking.
