Why remove a sentinel lymph node that shows no sign of disease?

I am reading recent studies that question whether sentinel node biopsies are necessary before mastectomy for DCIS. , Especially if the DCIS is only visible on MRI, has no palpable mass, and in women over 60.

The possibility of lymphedema seems to be causing doctors to question whether SNB is needed. If invasive cancer is found post-mastectomy, would the sentinel node provide any important information we couldn’t find out using the removed breast tissue? Are micro-invasive cells too easy to miss when looking at whole breast removed tissue?

I may be wrong, but it was my understanding that with the SNL, there wasn’t a risk of lymphedema, the risk comes if they have to do additional incisions with removal of all lymph nodes.
