I've recently stumbled across similar errors to #3735 and applied the proposed fix there - created a new ShouldRetry function for the storage client. However, it seems very odd that I have to copy the code from the default retry function - which also means that any additions/fixes to it will not be reflected in my code automatically. I think it would be nice to have that function exported from the storage package, so it can be used like that:

gcsClient.SetRetry(storage.WithErrorFunc(func(err error) bool {
	if storage.DefaultShouldRetry(err) { // this function comes from the storage package
		return true
	}
	return customShouldRetry(err) // my custom retry logic
}))
