It is possible that if major hiring demand gets high enough, some regionals will not be able to staff their flying and that could result in consolidation and some shutdowns.

Silver lining is that *somebody* will hire you immediately at that point, or you will get transferred with your planes to a new regional. Unlike 2020/covid if regionals are failing due to industry-wide staffing shortages there's not going to be entire pilot groups cast adrift with no employment prospects.
