Question: should this library footprint adds 327 Kb to vendor chunk in angular cli build?

[daBishMan]

Description of the Issue and Steps to Reproduce:
I think the footprint for this library is too large, is there a way to reduce it?

Did you search for duplicate issue? [Yes / No] Yes

Please describe the issue and steps to reproduce, preferably with a code sample / plunker:
I have an enterprise application and when I import the MomentModule to app.module imports the vendor bundle size is increased by ~300kb, the build command I used is

ng build --prod --aot --build-optimizer -vc true -cc true -ec false -scd --named-chunks

this is can be replicated using the CLI and new project using the following:

Angular CLI: 1.6.3
Node: 8.9.3
OS: win32 x64
Angular: 5.1.2
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router

You can see the decrease in vendor chunk.

This probably have to do with moment locales being bundled in - see #127 / #168 for a workaround, also see angular/angular-cli#6137 for discussion

[liluxdev]

how to select language for displaying time ago strings at runtime?

[urish]

See #197 for a workaround that doesn't require ejecting or moving files around after every package update
