But they did change their mind.

Blizz tells gamerrant they want Wrath to "Feel like vanilla"

Hi Everyone, Just wanted to pop in and say that we do in fact intend to implement the quest tracking features that were added in patch 3.3 of original Wrath of the Lich King into the Quest Log and Map UI at some point. The interviews linked by the OP were a few months old and our thinking has changed quite a bit on this since then. This feature isn’t present on the Wrath of the Lich King Classic beta at this time, but this along with several other UI features such as the Calendar and Equipment…

Best of luck with getting them to try your suggestion, OP.
