What does the return to Level 4 restrictions in Thailand mean for visa runs and inter-provincial travel?

The recent announcement that Thailand has returned to Level 4 restrictions raises concerns among expats regarding potential impacts on visa runs and inter-provincial travel. Previous escalations of restrictions have resulted in significant limitations, including reduced public transport services and potential curfews. However, since the last increase, some visa runs to Cambodia have been conducted, and inter-provincial travel may still be feasible. The community appears uncertain about the extent of restrictions that will be enforced this time, especially given the mixed experiences after the last level change.
