This sounds interesting to me.
As far I remember, I have never seen such strange results of latexmk
under build envs where all the necessary packages are properly installed.

I think what you are trying here is to paper over whatever bug in latexmk/
xelatex by always ignoring their exit status.  Am I guessing right?

If that is the case, I'd rather report such an issue at upstream
lagtexmk/xelatex.

Can you please provide a reproducer of such an issue?

Or you saw something while you were tackling issues you claimed in the
cover letter [1] of "Fix PDF doc builds on major distros" series?
