Source for this loss of security? I'm aware of the MATZOV work but you make it sound like there's a continuous and steady improvement in attacks and that is not my impression.
Lots of algorithms were broken, but so what? Things like Rainbow and SIKE are not at all based on the hardness of solving lattice problems.
