What should we do about our legacy tests? Would it be more sensible to use older GitHub Actions specifically for those tests, or should we consider removing them altogether?

Can you remind me if legacy tests provide extra coverage over what non-legacy tests do, that you consider useful?

[jorgebucaran]

I remember that the legacy tests are the same but run on older Node.js versions. However, on closer inspection, they do include some environment tests not present in the current tests haha.

[kibertoad]

we should migrate them, then, and then we can drop the legacy ones
