Should Build plugins be required to be cross-platform?

[ehmicky]

Node.js is pretty good at abstracting platform-specific differences, but there are many ways to still write Build plugins that do not work (usually) on Windows.

Our production machines run on Ubuntu, but builds triggered through the Netlify CLI can be run on any machine. As many surveys show, a big proportion of developers are actually using Windows locally.

Should Build plugins be required to be cross-platform as part of our guidelines and enforced through code review?
