You want Polymode: https://github.com/vspinu/polymode

It is confusing alternating between the Org major a mode and the
source block major mode as you scroll through documents. One second
you are an author for humans and the other an author for the computer.
That is how literate programming is defined in theory, but in practice
I don't do it like that because it is mentally jarring.

I spell check my Org-Mode Literate Documents. But the spell checker
does not check source blocks. That is up to the major mode for that
source block, not for the containing literate document. When you think
about it, probably every Org-Mode literate programming has it set up
this way, otherwise the spell checker would go crazy on typical source
code. That is revealing. The source blocks are very different "things"
than the containing document.

For me the source block is another cognitive workspace that I enter
consciously. I am digging deeper into the document itself. For me the
source block is a window into that world of the source block. In the
top level document I write literature about things, including the
various source blocks. Then I jump into editing the source block
itself.

John you once had a discussion (or answered a (my?) question) about
making source blocks not-editable. That is how I would like it to work
all the time. That is why I don't fontify source blocks natively and
that is why I wouldn't enjoy what you describe.
