Enhancement request: Track product "lifecycle"

It would be great to support lifecycle events at the product level.

For instance, when I have a portfolio of products and product releases:
- some products are end-of-life
- some versions may be end-of-support

... And so on.

This is important for vulnerability management: if a product is no longer supported, I will not want to manage vulnerabilities the same as for a supported product (or may ignore these entirely)

There is a project at CycloneDX for common lifecycle events that may be of interest for this domain.
