It would be nice to have (semi) public API to inject custom build commands into the build_name.{sh,bat} files.
My specific use case is to generate a bash script that contains a base64 encoded version of the bit stream that loads the bit stream automatically via the linux fpgamanager infrastructrure on a zynq.
Currently, I am having quite a hack in place to implement that but that constantly breaks and is a very bad solution.

For me live would be easier if TemplatedPlatform had an extra_command_templates property that is guaranteed to be not a property object and therefore easy to override.

This sounds like it should be a part of an external programmer. Could you explain that workflow in a bit more detail?

At first that logic was inside the toolchain_program() function of the platform but I realized that I want that bash script to be generated for later use even if I do not program the FPGA directly. I see that file a bit more like what a svf file is compared to the normal bitstream format.

Ack, that makes sense. I'll see what can be done.

My workflow involves generating that file (which also contains other stuff from the design like a memorymap).
This file is then copied over to the zynq via scp and executed via ssh in the toolchain_program() function.
