Agree with that fully. I only once supplied a native file which had a rectangular pad each side with very dense vias. The idea was to try to solder a power-pad type mosfet through the board as I had no reflow kit.  I got the solder resist layer just so, but they threw it away, looked only at top and bottom layers, and tented over every single via because "that is how we do it, if you want specifics then send Gerbers". I now send Gerbers :)
