Pundit, why is nilote languages classified as Greenberg's wastebasket

In his book The Languages of Africa (1963), Joseph Greenberg named the group and argued it was a genetic family. It contains the languages which are not included in the Niger–Congo, Afroasiatic or Khoisan groups. Although some linguists have referred to the phylum as "Greenberg's wastebasket", into which he placed all the otherwise unaffiliated non-click languages of Africa,[2][3] other specialists in the field have accepted it as a working hypothesis since Greenberg's classification.[4] Linguists accept that it is a challenging proposal to demonstrate but contend that it looks more promising the more work is done.

Africans are busy studying gender and feminism at college, meanwhile we are still relying on 1700 linguistic classification

Most of Nilo-Saharan languages
I believe Nilotic is quite solid - except for Southern Nilotic (only spoken by Kalenjin-Datoga) which is quite different.

So many - for example Kalenjin ideally should be  Nilo-Cushitic language. Kalenjin have about half cognate/root words that are nilotic and half that are cushitic.

Cognate or root words are NOT LOAN WORDS.
