But Evdberg, with respect, that is the inevitable consequence of parallel or divergent software development paths; at some point a change in one path will be incompatible with a change in the other. Software updates are bundled into releaases for good reason. You believe your version is superior but you can't complain that you don't have access to features delivered in the other path unless you, not Meridian, are prepared to support both paths. What would Meridian base their next upgrade release on: this one, the previous one, both?
I don't think Meridian are being intentionally awkward, they are following good commercial software development practice. Having worked for a software company that lost control of its parallel development paths and went under I know the consequences and sympathise.
Please don't take this as any criticism of your intellectual results or your yearning for improved sound quality in the face of what seemed to be a slow upgrade cycle.
