This is pertinent to #109930 from Validas as well, and they would like something like this to be included by default to make it less confusing for users of MC/DC.  On the other hand, as I point out in the issue, I think introducing MC/DC for single-conditions is redundant (given branch coverage) and introduces unnecessary overhead. So, that's an argument for keeping it as a separate option and perhaps finding another way to work branch coverage into the overall MC/DC metric.

Also, Branch Coverage gives you counts for switch statement cases, whereas I'm not sure that makes sense for single-condition MC/DC, though perhaps that's overkill.
