It's not an objection, it was an observation.
I was appalled when I first heard a colleague use "nonce" in this manner, I'd only previously heard it used as slang for sex-offender/paedophile, https://www.collinsdictionary.com/dictionary/english/nonce
That use of "nonce" supposedly comes from a once used acronym associated with some segregated prisoners..."not on normal courtyard exercise".
I'd heard the same, but half-expected a backformation
But it's a "nonce": to be used once, on a small desktop machine (for low-integer values of once). That's not really a good objection.
