It couldn't because even today it is still fairly difficult to convert existing code to the limited API. Some code cannot even be migrated at all, e.g. because the entire buffer protocol is missing from it. Some bugs were only fixed in Py3.9, time will tell if anything else is missing.
The only major project that I know has been migrated (recently, with a lot of effort) is the PyQt project. And a GUI toolkit probably doesn't have all that many performance critical parts that are dominated by the CPython C-API. (I'm just guessing, it probably has some, somewhere).
I created https://bugs.python.org/issue41111 to propose to convert a bunch of stdlib extensions to the limited C API to eat our own dog food: to ensure that the limited C API is usable, or not just a "technology demonstration".
I listed missing features of the limited C API, like getbuffer and releasebuffer.
We are adding a C compile mode for the limited API to Cython.
That's really great!
