Any good reasons to file - or not file - FAFSA?

Most schools will allow you for file a psuedo amended FAFSA if you have exceptional circumstances (e.g. FAFSA is based on 2016 tax filing, but your 2017 income was at least 30% lower). You have to file the "original" first and it is generally not until late spring that they allow you to file an amendment.

Where can I read about this? I might retire a year or two before the oldest starts college, and the timing could be crucial, especially since they moved the tax year they look at one year earlier (I think, still learning about this). What's it take for them to look at the more recent year?

I would definitely file, and can probably get income and assets below key thresholds (definitely income below $50k by that time).
