Creator here, happy to answer any questions about what it takes to build a collaborative Wiki for tracking support life cycles.

Thank you for making it. - Would like a time line view: as of the next few months, what are expiring. - Would like to see a stability score for a Product / Stack, you define the metrics for what is considered stable vs obsolete. How it compares with other similar categories.
Second is very subjective. If there's onething that I've learnt over the years working on this - it is that the definition of "support" is very fuzzy. You can't even compare what "LTS" means between different stacks/products, so it is hard to objectively rate anything. It still might be worth doing some analysis and publishing as a blog post though, but i'm not sure if it can be automatically calculated.
