Python code and resource-constraint device don't seem like a good combo in terms of performance. Is it just for prototyping?

Only in the same sense as interpreted BASIC in 8 bit home computers, with their 64 KB RAM, single digit MHz, tape loading.

Good for prototyping and introduction to programming, then you had to switch to Assembly for anything meaningful.

Here, you might switch to Assembly like in those days, or maybe C, C++, Rust, Zig, whatever.

Some I know use it in production for iot in remote factories where internet isn't reliable.

If anything needs to be fixed, anyone with a computer can connect on the USB port and push new pythons files, without the need of an up to date dev environment.

Usually performance isn't that important as those devices handle a few events per second.
