Hi Brian,

That is interesting, but are you aware that it is not a list of features already in Blender? It's a fundraiser and wish list of some potential ideas for the future.

Whichever developer takes up that task will find pretty quickly that Booleans and Fillets are an enormously complex area and cannot be easily coded from scratch without many many man-years of effort just on those areas alone.
