The roadworks are still listed, but you won't see them unless you select filters that include completed works. Current status for the Reading Road and Thornhill Way works is: "Work completed (with excavation)"
It's common for Openreach engineers to visit cabinets in support of the plain old telephone service (POTS), but I didn't see any significant activity near the VDSL2 cabinet itself; I was hoping to see some groundworks to connect the cabinet to the power ducts hidden in the nearby verge.
I'll give it a couple of days and see if the checker updates. It's crazy to think this cabinet was installed last July and has been doing nothing other than depreciating ever since.
