Why are max endstops disabled for CoreXY in Marlin?

I was reading through the Marlin source to try and understand how it works (I'm currently tinkering with CoreXZ support), and came across the endstop handling code in stepper.cpp. Even though MAX_ENDSTOPS are force-disabled for CoreXY, it seems like it would be trivial to enable them with an additional "if else" statement--almost too trivial. Is there any reason why this has not been done before?

I'd post code snippets, but the code formatting doesn't seem to be working properly.

Hi there, did you get or find an answer to this please? I am running into similar issues...!

Because there are not supported on the old release. Take the newer RC instead.
Or commit it and free your endstop after each homing.
Like:
G28 X
G1 X100; free the endstop
G28 Y
G1 Y100; free the endstop
G28 Z; or do what you want.

[ Even though MAX_ENDSTOPS are force-disabled for CoreXY ] ???

I am using Marlin firmware for a CoreXY machine using 7 endstops:

X axis - 1 x Min and 1 x Max endstops
Y axis -1 x Min and 1 x Max endstops
Z axis - 2 x Min and 1 x Max endstops (using 2 stepper motors for z axis, I have the Marlin auto syncing the 2 stepper motors when homing to Min position (Using two Min endstops ,e.g. Z1 Min & Z2 Min ).



Only issue I have is there a set time frame for homing and syncing the Z axis regardless of the position of the Z axis platform/bed. Not a big major but still would be good not to have it.
