I've been out on the AT in MA nearly every weekend this winter. The Goose Pond site and the Shaker site are not on the closure list as they are not on state controlled land. That said, I haven't seen anyone at any of the other sites I have used this winter. Some of the closure signs say "for the 2020 hiking season" some say "until further notice." The Mt Race section has been my favorite so far but I haven't made it up to Greylock yet. I would highly recommend something over Mt Race. It's about as extended of a ridge walk as you can get in MA with awesome views of the Catskills. Sages Ravine has a bunch of private sites, many with platforms. Laurel Ridge might give you some more privacy due to lower usage and there are a couple platforms there. Race Brook has some platforms but the site was heavily impacted and I decided to move on instead of stay there. Crystal Mountain has some pads and you could do a hike up to the Cobbles one day but it's right next to a power cut. Race Brook Falls to Sages Ravine would take you past 4 waterfalls and an amazing ridge walk, you could head over to CT and do Bear Mountain for a dayhike, though I'm not sure if that's a worthwhile endeavor given my limited experience in the area. Should be noted that fires are not allowed at Laurel Ridge or Sages Ravine, though they are allowed at Race Brook.
