Kotlin to support package protected visibility

I don’t see that in this thread. There are a few people here that don’t think package visibility is necessary for kotlin and others who argue it is. Yes AFAIK JetBrains is part of the first group (or at least they used to be), but I don’t think this can’t ever change.
There are good reasons to implement package visibility. If you guys are serious about it you should write a KEEP for it as this is the official way of changing the language. Whether it get’s approved is another question but until then nothing will change.
