Merge with importmap module

Thanks for listing the differences.
FWIW

A way to declare imports dynamically (something similar to hook_library_info_build)

, there is a standard alter hook here courtesy of the plugin manager so that is supported.

But you're correct, the other three aren't supported.

I think we'd be better to try and get this into core by 10.3 and mark both issues as deprecated?

I'm not using this module in production anywhere (and there is no tagged release). So I think I'll deprecate it now and update the project page to point to yours and the core issue.

Ah I did make an alpha release, I didn't realise. Either way updated the project page to point to your module and added a note about the core issue.

Automatically closed - issue fixed for 2 weeks with no activity.
