No, the interpretation of the word reservation was not the historical meaning. Changing words to mean more pleasing things is still not telling the truth.
This is tangent to my arguments against using the new term "differently enabled" as opposed to "disabled". "Disabled" indicates that there is a problem that society needs to spend some resources on to correct and fix. "Differently enabled" is some politically correct term that seems to mask a problem and make people feel ok when they shouldn't.
Perhaps only nominally so originally, but that doesn't mean it can't be used to advantage now.
