I think they’re mostly keeping them around to keep the technology alive. As a lone platform, there’s nothing wrong with them, but doctrinally it’s clear that they are more of an afterthought.
There is for example no initiative to port cutting edge technology from the conventional fleet to them.
The nuclear strategy has always been focused on interception and defense first. The reasoning is fairly simple. If SSBNs are used, it means the war is already lost, the only thing left to do is to also destroy the enemy as well.
Nuke proof and ABM covered silos can do the same thing, but they can also shelter people and reduce enemy attacks, which is the only way a nuclear war could potentially be won. SSBNs were required in the early Cold War due to the poor range and characteristic of the land based missiles.
