What happened?

👋 howdy, team!

ILM Rollover is not inherently compatible with Index date math (because you'd have to daily manually bootstrap the new index). Therefore this ballpark that I've fixed before needs some more love, sorry:

It needs to effectively say it's an either-or choice: use an index with/out date math or use an alias/datastream, but don't join those ideas together which is currently how some users are interpreting this.

Additional info

I believe the edited content will be under https://github.com/elastic/logstash-docs-md but this repo's new to me and I'm not sure how to make this desired change if you'll kindly show me how. 🙏
