Why do scRNAseq pipelines (e.g. seurat) have the filtering step to remove cells that express over 2500 genes? Meaning, why 2500?

Does anyone know how this number became "default"? what is it based on? How deep is our knowledge of "average" , "healthy" gene expression of different cell types? Sorry if my question is trivial...
