Credit a production-ready Filament build
Compare against shared Blade components, Laravel policies, Actions, Data objects, selected packages and proper caching. Both approaches can support the same public output and one shared-view design change. Filament resources and structured editor fields are already useful tools. Capell adds another model and dependency surface; adopt it only when its coordinated Page lifecycle is worth that commitment.
Capell supplies Page history, comparison and validated recovery, URL/content lifecycle conventions and maintained CMS integration. A competent custom CMS can implement equivalent behaviour. Both still need the appointment association, domain rules, permissions, prepared-data adapter, views and freshness integration. If the existing CMS meets those requirements, migration may add little value.
