Perhaps not with rock solid consistency, but we've certainly used the
argument of the "not a major major version release" to shoot down
introducing incompatible features / improvements (protocol changes
come to mind), which further lends credence to Jim's point about
people expecting backwards incompatible breakage to be in a major
major version changes.
Given the overhead from a development standpoint is low, whats the
better user experience: delay removal for as long as possible (~10
years) to narrow the likely of people being affected, or make such
changes as visible as possible (~6+ years) so that people have clear
expectations / lines of demarcation?
