Should the keyword "reenacting" be merged and mapped into "reenactment?"

I recently came across this post by @mbmb, which reports two keywords that were merged and auto-converted by IMDb staff into the "reenactment" keyword:

re-enactment

reenactments

Seems like the following keyword should also be merged and mapped (auto-converted) into "reenactment":

reenacting (2 titles)
