What are you trying to solve here?
I wanted to make the partition user-mountable such that I can mount it before upgrading packages. The partition would not be mounted by default. (`noauto,users`) Then I found out that it defaults to ownership of mounting users, which is not good.
As I mentioned previously, I would argue that the ESP should always mount with owner 0, even if my use case/experiment itself is an outlier. I spotted my mistake, but was surprised by how owner is chosen (in such a case).
Yes, even when using sudo this shouldn't be a problem, however the behavior does deviate from other filesystems which have their own permission bits therefore have "protection" (maybe a strong word) against this situation.
