Absolutely not - while technically ambient and emission essentially do 
the same thing, they reflect two entirely different use cases, which the 
previous ambient-only mechanism could not both cater for simultaneously 
without different material definitions for radiosity and non-radiosity 
scenes.

As a matter of fact, the two have been separated in POV-Ray 3.7 so that 
carefully designed textures can now be used for both radiosity and 
non-radiosity renders alike without change; the key is to design the 
texture to work in a radiosity scene first (for reflective materials 
make sure to use a light probe in your testing environment or otherwise 
provide some environment to reflect), then add some ambient to lighten 
up shadows in non-radiosity renders.
