No? It's been like that for decades.
Crux Terminatus exists on terminator armor shoulders, it's there as a symbol of veterancy but also in-universe the people believe that it contains a shard of the Emperor's armor.

Terminator Honors, however are just a smaller badge shaped like a crux that is given to veteran marines to signify that they have earned the right to wear terminator armor, and you mainly see this if the veteran marine is just wearing regular power armor.

You can see this in pic related. It's that one captain model from 1991, and it also has a terminator honor badge.
