Not in my experience. Replacing bridges and redesigned string scales with new soundboards with added cutoffs and new rib scales, longer back scales, transition bridges, log progressions across breaks, and silent and functional front duplexes is becoming more common every year. Just as action geometry analysis and correction has become commonplace as we became aware of the need (in ill-designed high-to-mid value pianos), we who do this work are finding it well worth the trouble and expense in performance enhancement. The folks for whom we do it agree. Ron N
