acr_values limited to number of values

I have a customer who is running into the issue detailed here "options.oidc_metadata.acr_values_supported" must Contain Less than or Equal to 20 Items in that the acr_values returned as part of their connection properties is over 20 items so we cannot use that to create a connection.

2 questions for the community

  1. what are these used for? My app has no need so not sure why there is the limitation
  2. Is it possible to get the limits removed?
