We may want to make this page more generic:

FYI, as of October 2024, this page hasn't been used much. Based on conversation on dev list, it was really used during a specific effort to deprecate a wide variety of features in Solr as a "working" page. Please do not use this page as a summary of deprecations, instead use the Solr CHANGES.txt and "Major Changes" pages in the Ref Guide.
