It isn't very useful to say X is bad, let's not do X, without looking at what it costs to not do X. To give one hypothetical example, if it requires just two additional full try pushes to avoid one backout, we haven't actually saved any computing time. - Kyle _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
