because sometimes not only in late game also in early game you have to deal with biters.
If these biters came trough your walls and Not have enough resources to build enough turrets then the biters maybe completely destroying your base (That happend to me quite a lot times

the research could also be infinite, like every upgrade +5% health or somthing (Or maybe less)
Iam not a good Factorio Player but i really enjoying the game and want to improve myself and i feel like this research could make me feel more safe in my base

This is simply a Quality of Life Change in my opinion
