Lots of us had high magic settings with 1E, inspired by Elric and other big magic fiction. Pretending high magic is a modern thing is not very convincing.Re-check that.
In 1e, Bard was an optional prestige class. Yes, Magic-Users, Clerics and Druids had spells, but Druid shapeshifting? That was a 7th-level ability.
As for the others, yes, Paladins had some magical powers early. They got Lay on Hands, Detect Evil, Protection from Evil, eventually gaining Turn Undead, and even more abilities if they had a Holy Sword. But their spell-casting didn't kick in until Level 9 (yes 9!).
Rangers didn't get any magical powers or spell casting until 8th-level, at which point they got 1 -2 first level druid spells, eventually adding 2nd-level spells at 12th, and 3rd-level ones at 16th. Level 1 Magic-User spells followed at Level 9, followed by 2nd-level ones at 13th.
From 1st to 7th-level, the Ranger's magical powers were non-existent. Zero. Zip. Zilch. Nada. That is vastly different from getting a pile of spells and supernatural abilities starting at 1st-level.
I recognize this is a flavor distinction as much as a power one. It's all about the feel of a setting, not power level. Part of it is that the ubiquitous magic hurts my ability to suspend disbelief - a lot. I want magic to feel magical.
Magic in baseline D&D feels...productized.
