Hi,

With the current implementation, the process crashes if it calls 
lists:seq(N,M) with M<N. (A crash means an unexpected)
With your proposition, the same process will continue to do things but 
using an empty sequence.
For me, this is a big difference and all running applications must be 
checked to ensure that they can handle empty sequence correctly.
