SUMMARY After the release of KDE Frameworks 5.66, the appearance of the taskbar buttons was changed and now they don't look in the same style. For example, the hover button in all three states (minimized/normal/active) looks the same. Also, the background color for the minimized and pinned buttons is almost indistinguishable. Therefore, I'd like to propose to unify the appearance of the task manager buttons. The proposed appearance can be seen in the attachment. As for me, it looks more informative and elegant. It would also be very cool to be able to customize the appearance of the taskbar (some tweak tool, config file, etc.).

I didn't mean "restore the appearance", but meant "unify the appearance". I guess that you haven't even read the description of this bug report.
I did, and I looked at the screenshots too, but "unify" isn't an accurate term to use for describing your proposed changes. You're asking for the styles be made more distinctive, not the same (which is what it would mean to unify them).
