Not that i have objections against this change, but changes to the software/userinterfase of the Wikipedias should be announced formaly and well in advance. Somthing like this; Give 3 weeks notice.
This is way too long. I don't have time to track each individual patch over three weeks, especially since patches become obsolete quite quickly as other changes are committed. Besides, intwiki-l is not for feature discussion (see the list description). wikitech-l is, and if feature discussion concerns wikipedia policies, it should be copied/moved to wikipedia-l.
Notice that the above policy is not used by anyone else either, so I don't even see why you bring it up. Members of the international Wikipedias that want to take part in feature discussions should subscribe to wikitech-l and/or wikipedia-l, if we spread this stuff over three lists, we'll never get anything done.
What I can agree on is to send strings that need to be translated to intwiki-l before committing a change, and to wait a few days for translations to come in, then to commit the change together with the translations. But if not all translations come in within a reasonable amount of time, they will have to be added later, meaning that the user interface will have some English in it until the translations are submitted. If you check some of the international Wikipedias, you will notice that this is the case for quite a few of them, for features with which I had nothing to do.
