aws-cdk-lib: the package seems no longer lazy-loaded

[tmokmss]

Describe the bug

Hi, I just saw the release note and tested the time to require aws-cdk-lib module, expecting it's got faster from 2.98.0. However, as far as I tested it actually got slower.

2.97.0: 214ms
2.98.0: 1044ms

Looking at strace, it seems that the modules in aws-cdk-lib are not lazy-loaded any more in 2.98.0.

Expected Behavior

I don't know it's expected or not, just creating this issue for visibility.

Current Behavior

Requiring aws-cdk-lib package takes longer time than previous versions. I think it's still fast enough for running a single cdk app though.

Reproduction Steps

Install aws-cdk-lib:

npm init -y
npm i [email protected]

Then run the following code:

// index.js
console.time('require');
require('aws-cdk-lib');
console.timeEnd('require');

node index.js

Change package version and rerun:

npm i [email protected]
node index.js
