Historically-informed light construction displaced piano-frame construction as the dominant harpsichord-building paradigm by the late 20th century

Per Wikipedia's "Contemporary harpsichord" article, "with time, such [historically-informed, lightly-built] instruments came to dominate the scene, and the older heavy-frame instruments are almost never manufactured today." This is presented as an uncontested, settled description of the field's current state rather than a surprising or contested claim, so it clears the historical/status-claim sourcing floor at Tier 4 without needing escalation — sources.md permits Tier 3-4 for uncontested historical or status claims, reserving the Tier 1-2 floor for claims that are surprising, contested, or otherwise load-bearing.

The claim should not, however, be treated as load-bearing beyond "the general shift is real and durable" — it is not independently corroborated at Tier 1-2 in this session, and no count, date, or percentage is attached to it.

This is the durable outcome of the reversal Hubbard and Dowd began in 1949: the piano-derived "revival" construction paradigm that dominated the first half of the 20th century, exemplified by Landowska's Pleyel, is now the minority style rather than the majority one.
