The suction line accumulator is designed to keep liquid refrigerant from entering the compressor while still allowing for oil return.
The trouble is that if the oil return port/screen clogs, the accumulator can fill with oil and actually cause the compressor to fail. In addition to that, it can hold contaminated oil in a burnout.
As standard compressor replacement practice, you may want to consider removing the accumulator and dumping / properly disposing of excess oil to both remove contamination and check for excessive oil buildup as well as acid testing the oil.
In the case of a bad burnout, it may be best to replace the accumulator completely in addition to the other burnout protocol measures.
