I assumed that people using "pavillon" instead of "pavilion" simply made a typing mistake.
E.g. using "railway_staton" deliberately to describe something different then a "railway_station" is an example of bad practice in my opinion.

And btw. it wasn't an automated mass edit but I visited all occasions one by one to do the change in good faith as I considered it (and still do) a "typo"
If people do want to use "pavillion" and "pavillon" next to (the wiki described) "pavilion", there should be a mechanism preventing them for doing so. Unfortunately there isn't.
