:That was probably a dangerous thing for me to say, because (a) I was relying on memory, not an actual review of the discussion, and (b) my memory is deteriorating rapidly with age. I'm still pretty sure that was a real concern at the time, but no, I can't recall where that discussion was.  Maybe do some detective work on when earliest edits to WP:Tempate editor were made?  History of WP:CENT?  Ask at VPP, where people who probably felt passionately pro- or passionately con- are still hanging out?  Sorry.
