Stop overthinking.
With mesa hardware you don't need a base thread, only a servo thread is required. With that, latency isn't such a huge issue either. Trying to get an extra bit here and there does nothing.
The pre made image Rodw recently linked to is perfectly fine to run a machine, the only exception would be if you are using the RPi 5 spi interface to talk to a 7c81 or 7c80 as this requires a driver that isn't included in Rods image , this is not required for ethernet.
Invest more into learning the ins and outs of hal . This is more important that fussing over software as the images provide what is required, remember the only task these images are meant for is running a CNC machine.
If one reads the online docs one will fine some simple exercises that do not require a CNC machine.

Dear jjdege.
How can you solve the error when you install the ethercat package by command "sudo apt install -y linux-headers-(uname -r) ethercat-master linuxcnc-ethercat?

I read your post and it took a while to sink in how well running the native RaspianOS with the 6.12 kernel for what I want to accomplish.  I'm guessing that 6.12+ might be a real game changer across the board but I remember discussions about certain run-time flags being used to determine if PREEMPT_RT was part of the build and people commented that some don't match up yet.

Do you think that might be a hurdle in the short / mid  term?

Do you think someone familiar with the run-time testing code might already be working on a fix to any of those problems?
