Quite so.Because it implies that the only solution to martial versatility or utility out of combat is to also make them casters, which is a non-answer for some.
There are TTRPGs where everyone selects powers from a set of generic templates and flavors them as appropriate for the character. A wizard taking the "AoE damage blast" power stipulates that it's a fireball, while a more martially inclined character would say that it's a cloud of throwing knives or a series of dashing sword strikes. The mechanics are abstracted to the point that they use the same ability rules even if the in-game manifestations are different.
D&D is not one of those games. Powers and abilities have much more specific flavor. Your character class has a meaningful impact on multiple levels of play. And for many people that specificity is a major selling point. The more free form and abstract games leave them lost and confused. Given the choice between modeling clay and Legos, they want the Lego set.
Now, even this choice is a spectrum. Some D&D players are more comfortable bringing some of that abstract ethos in and doing reflavors or reskins of existing mechanics. But that doesn't come naturally to everyone. Some people will say, "But I want to be a Fighter and if I change all this then I'm not a Fighter anymore." That was a lot of the pushback that 4e seemed to get. The classes had much more even access to abilities, but for a lot of people it came at the cost of the character and identity of the classes.
I don't know if there's a good solution to let us have it both ways, where non-casters scale as well as casters do at high level but aren't just getting knock off copies of Wizard spells. Certainly no one's come up with one that pleases everyone, though many attempts have their smaller bands of adherents. If anyone does come up with one it'll certainly be a major improvement to the game.
