By the way since the questions is never if we drop support for a system but when do we do it, would it make sense to track / measure of how much work went into maintaining a particular system in the last x month (or will be in the next month like in the e10s case)? I guess that data would help to make this decision easier and with less debates (although there are ofc always exceptional cases for fundamental releases like e10s). - Gabor _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
