Personally I do a lot of typos and also see Lintian often nag about typos, so I think some spell checking is useful.
Alternatives to codespell would be spellintian, or debputy --spellcheck, but in my experience they have more false positives and no mechanism to override such occurrences. Suggestions how to implement a better spell checking (and automatic fixing) are welcome. I don't think removing it completely would be a satisfactory solution to the need.
