That's probably true, but it's the constant theme running through any news coverage of this proposed garage. I think for neighbors a pleasant maintained retail parking lot sounds like a better proposition than trusting the T and walking by a industrial site.
That said, this is possibly crazy pitch territory, but is there any reason that the T shouldn't persue a land swap with the Home Depot once it acquires the site? I know the T seems to have already committed to the Lowe's but 15% design is a fairly low bar, and feels like the T can justify purchasing the site, say it's tried, and here's a better option. It's basically identical use for the Lowe's site, which is actually slightly bigger, with a bigger newer building, with much better visibility for retail, about the same parking. A Lowe's and a HD can't be that different really. The current HD site is actually zoned Industrial, owned by HD corporate, so no leasehold issues, and while ~2 acres smaller, has much less wetlands. It's also tucked into a nearly invisible gap between Burgin, the station garage ramps and the tracks. No abutters at all, no ped access considerations, but it has what looks uncommonly like an Old Colony spur. It can't hurt the T to have a healthy chunk of land right next to it's rail RoW.
