Fast Refresh is disabled in your application due to an outdated `react` version

warn  - Fast Refresh is disabled in your application due to an outdated `react` version. Please upgrade 16.10 or newer! Read more: https://err.sh/next.js/react-version

Can this be ignored?

Hi @muuvmuuv

I think it can be safely ignored since Fast Refresh is React specific. Preact uses Prefresh and is included in this package as you can see here:

next-plugin-preact/packages/next-plugin-preact/index.js

Line 13 in a1819d2

 const withPrefresh = require('@prefresh/next'); 

Prefresh works like Fast Refresh for me. I ignored this warning message. Plus, with Next.JS 10.0.6 the warning no longer appears for me.
