In case you are not aware, Boost.GIL provides such abstractions [1]
It's not yet pure C++20 ranges, there will be at some point.
Although Boost.GIL design is a complex one, it's IMHO not trivial to beat
its feature-completness, flexibility, extensibility and performance it
can generate.

FYI, I have half-baked IO extension for GDAL.
I'm going to continue/finish it as soon as next Boost version is released
which should include completely new version of IO layer.
Then, it can become another one to compare in your benchmark.
