What did you think with Prepare to merge in some breaking changes.? Any specific Issue or PR already merged or not yet since last year?

And here to ask if a release and publish would be possible?
Merges for #242 and #243 are really useful but still not available since v6.1.0 two years ago.
Both cordova-android and cordova-ios still rely on "cordova-js": "^6.1.0" even on their current dev branches.
So should it be a v6 or v7 release I don't know, but it would be appreciated ; with following version update, builds and publish for both android and ios please, so that we can take advantage of these improvements and try to prevent some app crashes.
