I like the idea of simplifying the tool chain, but I'm curious how flexible Rome will be in terms of settings/customization. Like, if it "replaces webpack", am I locked into Rome's idea of what an "optimal bundler config" looks like? If I need more from a bundler, do I have to completely replace Rome with the "old" toolchain? How extendible is Rome on its own? I'm wondering if it will have something like CRA's "eject" that allows you to override the defaults, without having to replace entire portions of it.
