I disagree. Riemannian geometry became Italian school mathematics and physicists didn't know anything about it.

The formulation of special relativity using a metric was also the work of Minskowski, and Einstein head to learn it.

Lots of people worked in that direction.

The first metric theory of gravitiy was that of Nordstrom

There is also a famous Einstein-Hilbert dispute

Hilbert was done with the theory earlier than Einstein, and he was the one who knew the math, but Einstein came up with the general field equations.

And generally, there are articles from a decade after GR came out that make it clear they don't get the math (or it's implications) of coordinate transformations vs. curved spaces.

It's like with spin, the early physicists working this out had no insight into Lie-algebra homomorphisms, everything was foggy
