> I'm not sure if making zero DW_AT_low_pc special for executable/DSO in DWARFDebugAranges is a good idea.

That could be seen not as special value but as a value which does not clash with other ranges. For example Linker could(as an imaginary processing) assign address to the section and delete it after address assigned. In that case relocation could be resolved into this not overlapped area. Using UINT64_MAX-1 is similar to that handling. The difference is only that it simplified by taking maximal address value instead of assign an unused area.
