I thought there were some Chinese clones of the lower end STM32F series
but I haven't paid close attention.

I think current practice is to run your system inside a VM that you
snapshot so you can later reproduce it.  In critical systems you do that
whenever you make a software release, so you snapshot not only the
current source code (revision control already does that), but also the
complete tool chain including compilers, libraries, all the build
artifacts, and the whole OS.
