Thanks for the issue. Yes, it's a known issue, but now, with the current architecture, it can't be properly fixed.
core-js contains thousands of cases of specific features detection. Now, core-js contains ~600 internal and external modules, moving all such cases of features detection to separate files will increase this number to some thousands. It will make mappings of modules almost unsupportable and will increase the size of any significant bundles by tens of percent.
In core-js@4, ES3 / IE8 support will be removed, some cases of such workarounds will be moved to entry points and it will significantly reduce such dead code in bundles.
