I used to travel Boston to Richmond several times a year, but never thought of taking the train. My customer's building was on Staple Mills Road, about a mile from RVR, so it would have been extremely convenient. (They moved their computer center to Philadelphia in 2012 and I took the Acela there a bunch of times.) So a roomette on the 67/66 BOS->RVR->BOS would have been great!
As to "Why now?" The new VII sleepers are coming online, so they currently have a surplus. Plus the COVID service reductions might make more VI's available. Maybe they were planning to retire some of the VI's and replace them with VII's and decided to keep them in service instead and use the opportunity to increase service? That would definitely be a GOOD THING (TM).*
[*] there used to be a smiley for registered trademarks, but it seems to have vanished. There was both a circled "R" and a "TM", but both appear to be gone now. I suspect the Organization of Smiley Exporting Countries is creating artificial shortages to drive up prices.
