Excessive number of chunks in Angular downgrading performance

[albanx]

Command

new

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

No response

Description

I am not going to add many details as I see that this has been reported many times:
#26307
#27321
#27418

But I would say this should be address, there should be an option to configure the chunk strategy.
When Angular was using Modules, and lazy routes the chunk strategy was simple based on lazy load modules.

Now I think this has got out of hand, networks connection/devices are not the same for all users

Minimal Reproduction

Create a simple Angular app on version 17+ and observe the number of chunks.

Anything else relevant?

@mgechev I recall you last time were calling for community suggested feature, considering the number of times this issue is appearing maybe this can be a feature to consider in the next release.
