I feel thats the wrong way to look at it.
There are advantages to this as well.
If we had the steel available for a Micrograph we would see finer Carbides than CPM154, Sg2 and S35VN.
This SPY27 is also capable of higher hardness.
The idea with finer Carbides and lower volume is in most cases it leads to superior edge Stability if the heat treatment and Geometry is correct.
All this meaning in use the user will experience less chipping and rolling and a wider audience can use thinner edge geometry to enhance the edge holding rather than just carbides. Another benifit is folks that don't believe they need diamond for super steel will not have as much detriment to edge performance using a wider range of abrasives.
What we may see is that in real world folks will experience More edge holding with this steel over s35vn do to being able to make the edge sharper to start with and more stability.
Check out the article. It's inferior to S35VN. It's basically on par with CPM-154 for edge retention.
