I assume by "in the wild" you mean an "olde" usage, rather than something recent.

I mean something which was written before it appeared in Bailey's / Shipley's / Mrs Byrne's. For me, it's like the word dord 'density' in the 2nd Merriam-Webster. It wasn't a word, i.e., it didn't exist before, but it got added by mistake. After that, sure if somebody wants to use it, go ahead and use it. The funny thing is I don't see a society for promoting dord, but perhaps I should start one à la Bob the Angry Flower's infamous rant or the APS.

Ceci n'est pas un seing.
