Good to see an early adopter for the technology we awaited so long.  I concur that the lack of Segwit change address support is quite irritating.  That should have been done at least a few months ago.  But I will not so badly blame Core, given the sorts of time sinks which have sucked away developer effort since long before Segwit activated—and reached a time-sucking nadir in the past few months.  For but one of the more recent examples:



Reading in the recent release notes a list of “Network fork safety enhancements”, I can well imagine the internal monologue which must have gone through some dev’s head.  “I need to finally finish this patch for Segwit change address support (plus tests, tests, tests).  No wait, first I need to find some ingenious hack to ban fork nodes who lie about their identities so that they can waste node resources and try to subvert the whole network.  Network safety first.  Sigh.”

It requires prodigious engineering effort to produce mission-critical financial software which handles hundreds of billions of dollars’ worth of value, operates in a hostile network environment, and is never, ever allowed to make the sort of mistake which could drop huge amounts of money on the floor because somebody rushed the change address patch.  I’m so glad that Core gives this to you, me, and everybody else for free so we can run our businesses, whether or not we pitch in what we can for what is an open-source project.
