You may have to leave these in here empty. We should check the script_generator
logic on the infra side.

Some bots (Nexus5 Perf (3) as an example) were already missing. I do not think
getting rid of them will be an issue.

I don't actually know what happens if you remove these. The worst thing is that
they'll break, but you'll be able to revert quick...
