Nope, I just checked back in the archive and that's not what happened. There
was an extended discussion about whether to force users to use the silly KiB,
MiB, etc units. Thankfully the pedants lost that round soundly.
There was no particular discussion about case sensitivity though Simon made
the case for user-friendly behaviour:

There was a lone comment from Thomas Hallgren in favour of case sensitivity in
the name of consistency. But Nasby's comment was directly in response and
nobody else piped up after that.
