Don't load ICU formatting into bundle

[max-frai]

Is your feature request related to a problem? Please describe.

Hello, I'm optimizing my website and found with bundle analyzer, that big portion of js takes formatjs/intl-messageformat. I don't use message formatting in the project and there is no importing of this in the code. Is it possible to remove it from bundle?

Describe the solution you'd like

If we don't use message formatting, removing it from bundle would be great

Describe alternatives you've considered

This is tracked in #962.

Along with #1 these are the main features I have planned for the coming future of next-intl to make sure performance is as good as it gets.

As a side note, if you don't use any ICU features at all, I know that one user once set up an alias to the import of "intl-messageformat", to import it as null. It's a hack that can work for some limited cases.

AOT-compilation will be the thorough solution though that will work for all cases.
