This change is incorrect - "unacceptable" is exactly what the writer wanted to say here. jon

*it cannot be 'designed out' without inevitably degrading other portions
of the timers.c code in an unacceptable way*
equals
*it can be 'designed out' ... in an acceptable way*, I think.
So, just from semantics, my feeling is, *it cannot be 'designed out' in
an acceptable way* is the reason why integration is hard. Am I still wrong?

Am I still wrong? The original author, clearly, was talking about the degradation being unacceptable. It seems clear enough, I don't think that change should be made. Thanks, jon
