I think these checks exist, because of this line from the gabi.
In the first phase, input sections that match in name, type and attribute flags should be concatenated into single sections.
However, it should be noted that this is followed by an note that states that linkers are only **recommended ** to follow this approach.
AFAIR: at least gnu does not follow this rule. Also, I am aware of many codebases (games) with hand written asm which does not set the section flags correctly. This is not always easy to fix. Perhaps this asm is in a third party library etc..
Being permissive on this can be very helpful to users.
