Good point...
Where is the Blessed Sacrament; the center and core of our religion?
If the fight is fighting modernism -why look like them?
If the fight is to put the Glory of Christ the King in our minds, hearts, and in society, why not put him (the Blessed Sacrament) in the center?
Also, there is no liturgically need to go "behind" the altar, except in the rubric for incensing the altar at Mass. So why all of the "wasted" space behind the altar when our Lord in the Tabernacle can be rightly focused, Honored, and Adored?
In pointing this out, this sanctuary certainly looks empty and "dead", like the same conciliar modernism the present SSPX leaders want to make an agreement with -insane!
