As Phil notes, you'd need significant RIB scale (which does exist in larger networks) to require this…

I suspect that there is not that high of a risk of bugs due to this change, in all likelihood, the only changes required for this was a different compiler and perhaps the use of a few 64 bit instead of 32 bit variables — but even with a low risk of bugs, if there is no benefit, I’m not sure what the point of adding even a low risk of bugs.
