The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no additional preconditions or postconditions.

I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it provided. Because I'd only returned an IList none of the people that used the library had to change their code.

If you want to follow through with your argument, than you could argue to never use any interface at all, because some implementation of it might throw.

List happens to implement all three of those interfaces. If you expose your property birli a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they hayat modify the list.
