In addition to the paving operation that
@Doberge spotted in January, it looks like additional site work has been going on recently. On Saturday, I spotted a backhoe (which wouldn't be stored onsite during an extended hiatus) visible over the vegetation from one of the MK boats, and concrete storm pipes were plainly visible along the shoreline.
Comparing images from Google Earth from April of last year to February of this year, additional land clearing has occured along with grading, possibly for a new or expanded pond near the fresh asphalt. The concrete storm pipes and structures being stored on the northwest portion of the site also appear to be different, indicating that this laydown area is being used for semi-active construction.

The asphalt and curblines look similar to the southeast corner of the parking lot (near the C-109 label) on the original Reflections plans, with some modifications to connect to the existing roadways without the rest of the site being developed. This doesn't necessarily mean they're sticking with the original plans for the entire project, but it could explain how work is continuing without a new set of permits being filed.
It's also worth noting that Google Earth (and Google Maps) defaults to an aerial image from 2018 for all of WDW, even though there are about 10 images more recent than that date, showing the site prior to demolition. Given that it shows the entire resort from this period (including an incomplete Galaxy's Edge and Tron foundation), I assume the reason for that image isn't related to this site specifically, but it does make it easier to hide any work in this area.
As always with Disney, they're not just doing construction out of the kindness of their hearts; construction costs money and wouldn't be done without a distinct purpose. Whether that purpose is for the original Reflections project, a revamped DVC offering, or something entirely different remains to be seen.
