Because it is possible to remove but hard or expensive or even
impossible (was there a newline?) to add back if needed.

It is pretty easy actually:
import std.stdio;
import std.string;
void main()
{
string line = readln.chomp;
}
(Or with various combinations of parethesis and without UFCS. :) )
That works even when you wanted the whole string to be immutable:
immutable char[] line = readln.chomp;
Or, perhaps more preferably:
immutable(char[]) line = readln.chomp;
