I do the same, except for the "x" (that is, "set -euo pipefail"); depending on what you're doing, "set -x" might be helpful, might be too much noise, or it could even break things which were not expecting the extra output (and in the worst case, it might end up echoing secret tokens into your build logs).

I find it to be a good default when writing a script, but yes, it can get noisy and potentially leak stuff, if that is what your script deals with. That hasn't been a concern in the settings I usually use it, though.

I am not sure how it could break anything though, unless you are parsing stderr of your script in a subsequent step, which would seem unusual anyway.
