Since BinPackParameters: false / true can still be used with either approach, I assume the main worry would be that some stack overflow answer about an odd behavior / interaction of BinPackParameters that BreakParameters inherits will be less easy to find for people using the new option?

>One reason I suggested making the change without renaming the option was the level of flux the name change was having. I couldn't really see in the review what was a change for the name/enum and what was the new behaviour. (maybe that could be done in 2 separate commits?)

I'd certainly be happy to split the changes into 2 commits, if this is the approach you all want to go with.
