I disagree on that.  Afterall we do make that point of distinction.  Usually based on a very large change.

For example the development of lungs.

A giraffe with a small neck would still be a giraffe.   A Giraffe with lungs we would clasify as something else.

Bacteria no matter how much it evolves is still considered bacteria... until it makes bigger shifts.

Think of a car.  You could change it's color, extend a bumper, add cupholders... whatever... it's still a car.

Add a raft on the bottom and a propller and now it's a boat.

 

Thing is though there is no point where a animal suddenly has lungs compared to its parent that didn't have lungs. Its just a series of much much smaller changes that leads to that development.

 

Not true... there is a much larger difference in something such as lungs.  Even small changes to lungs or gills then there is in something such as changing size or color of skin.
