Changes to bp-default won’t happen very often, and if your theme is a child of bp-default, then you inherit these changes automatically. If not, then it’s your choice to adopt these changes or not.

I get what you’re saying, and it’s a valid concern. The ‘zebra’ class was added only because the JavaScript that was doing the striping was striping things all over the place that it shouldn’t have been. The only way to get it to stop reliably was to tell it exactly which tables it should stripe, hence the zebra class was born.

If you have problems or questions about it, ask them here or in IRC and I’ll try to help.
