Is it possible for Simulink to support m7 cortex for NXP and requires an third party tool?

As a automotive professional, I trust MATLAB & Simulink. But when it comes to third party tools, I lack trust as Mathworks cannot take responsibility for any issue caused by the third party tools.

I want to generate application code for NXP S32K3XX controller which is ARM cortex M7 tuned for double precision datatype with 6 stage pipeline. But generic matlab ert. allows only till M4(3-stage pipeline). I'll be using 32 bit single precision. Even though I'm not going to use 64bit double precision datatype, I hope there will be some advantages M7 compared to M4. I would like to know what kind of difference in the performance while using 32 bit single datatype in M4 & m7

If the performance difference is drastic, If Mathworks have any Idea to bring M7 for ert. codegen in future?
