Consider adding support for Really Simple Licensing (RSL)

• https://rslstandard.org/guide/what-is-rsl

Really Simple Licensing (RSL) is an evolution of the early ideas behind the widely adopted RSS standard, which provided a machine-readable framework for publishers to syndicate content to third-party clients and crawlers in exchange for traffic. The RSL standard extends and generalizes these concepts to include explicit licensing terms, enabling publishers to define machine-readable compensation and usage conditions for crawling and processing their content.

RSL extends the RSS feed format, enabling publishers to create standardized, public catalogs of licensable digital assets such as articles, images, videos, or datasets. When used in an RSS feed, RSL functions as an RSS module that adds licensing capabilities to the RSS element.

The RSL Collective is a nonprofit rights organization and licensing platform that uses the RSL Standard to bring collective licensing and bargaining power to the Internet, setting fair market prices for content owners, and simplifying licensing for AI companies.

1. Maybe it could be used to simplify payment to some news feeds behind paywalls.
2. Maybe it could be used to control re-sharing and anonymous views in FreshRSS for feeds with explicit licence terms.
3. Probably useful for people using FreshRSS to aggregate information used in other AI workflows.
