Sadly (IMO), this happens all too frequently. Upward compatibility suffers because most package authors are (naturally) interested in solving their own problems, and they don't get paid to think about others using their package who might be affected by an upward-incompatible change. This is a hard problem to solve unless we can find a way to pay package authors to take the extra time and effort to satisfy their users. Most open source communities are stricter about requiring upward compatibility than the Haskell community is.

It seems to me that if you have any thought at all for your library's clients the chances of this happening are pretty insignificant.
