There's certainly always a lot of effort going into that direction. The KDE community also has a goals voting process that elects multi-year community-wide goals (each goal gets their own leadership, funded hackathons, budget, etc.), and "Consistency" was one of the more recent batches and is still ongoing: https://community.kde.org/Goals/Consistency

So I'd say it's worth checking back, and certainly the developers/contributors take your ask seriously enough to vote for it themselves.
