That's right obviously. But the BOP will be probably adjusted before the race and Alpine will moan for sure. Also I think that ACO will "have" to listen to Alpine even just to don't hinder them so much. They (almost?) always assured the top speed edge , even minimal, so the will have to make up something to solve this.
On the other hand I think. there were times when LMP1 hybrids had slihghtly lower top speed than LMP2s (2016,2017? ) But then again, they had big boost out of the corners, so they passed then easily.
Anyway, somehow I have a feeling, that this time ACO doesn't want to hurt two non hybrid "manufacturers" to much and especially Alpine
