My last defense is, this is an extension, not part of the core protocol. If the burden becomes real we can always remove it. Modem-quality connection users may yell a bit, but the majority of broadband users won't notice a thing. But I understand if the answer is still 'no'. I find it unlikely that this cause much maintenance burden though, the packing algorithm has not changed for a very long time (most related change is pack bitmaps, which technically happen before pack-objects). The next big change (at least in public) may be pack v4. We haven't found a good algorithm for pack-objects on v4 yet, so there's a chance of problems there. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
