I trust the developers to know their game better than the players, frankly. We may have insights, but big decisions are best left to the professionals.
I like the philosophy of the Classic Mantra. I like how the developers have progressively made more changes to the Classic game as time has gone on.
Compromise with the barbarians at the gates has ruined some systems. Thinking we know better is hubris.

Access to dungeon content for low population servers is a big one. Access to low level dungeon content.
Well for one, it would be a distinct change from Wrath of the Lich King. Dungeon Finder was added in patch 3.3, about halfway through Wrath, and only existed in Wrath’s final major tier of content, well after dungeons were relevant. Putting dungeon finder into relevant content would be a very large change.
Everything else is entirely subjective: ‘anti-Classic’, ‘anti-social’, ‘beginning of the end’ types of opinionated doomsaying. Even subscription declines starting at the end of Wrath are hard to show or argue causation, despite typical scapegoats (‘flying mounts’, ‘lfd’, e.g.). It is a convenience for conversation trade-off, one that changes how players engage both with that content and other players significantly, and encourages problematic behavior. Full stop.

Could be, yes. You could offer LFD for normals-only, for example. Or only add it to 1-60 or 1-70 dungeons to deal specifically with the low-level dungeon issue. Or simply release it later.
I think normals-only is a poor idea. If players can spend their time in LFD normals vs grouping with manually in a heroic, that makes the playerbase of available heroic players smaller, making that experience worse for anyone wanting to run heroics.
A cross-realm low-level dungeon finder would be very welcome, I think. There is still a trade-off there but where it becomes a binary ‘do the dungeon with strangers’ vs ‘dont do the dungeon at all’, the pros do seem to outweigh the cons. Low impact for low cost, though, so if this is a significant amount of work, Blizzard shouldn’t bother.
Overall, I think the simplest solution is to do exactly what Blizzard is doing: kick the can down the road. Release WLKC without LFD, see how the playerbase engages with the improved LFG, and reevaluate releasing LFD at a later point.
