According to (second-hand) experience with auditors with respect to open source, they were quite open to considering things like CI, good commit messages etc. are useful when evaluating the development process, and even considered them sufficient (with adequate explanation) towards some of the ISO26262 requirements. However, that was for ASIL B only.
That matches our experience. They were super pragmatic. Also, their feedback was tough, but always technically grounded and from the perspective of "is the user always well informed?".
