A: Practical experience is that this is not a problem. And occasionally it happens, but not very often. Now, you see, the reason is that the users want interoperability and with free software the users are ultimately in control, and what they want they tend to get. The free software developers realize that they had better &mdash; if they are going to make incompatible changes they are likely to make users unhappy and their versions are not going to be used. So they generally draw the obvious conclusion and pay a lot of attention to interoperability.
