Bug: org-babel-tangle: persmission denied when tangling [9.4.5 (9.4.5-gbc2659 @ /home/n/.emacs.d/straight/build/org/)]

[No Wayman]

I'm tangling my early-init/init.el with the :tangle-mode header 
arg set to (identity (#o444)).
The idea behind this was to prevent myself from accidentally 
editing the tangled source files
instead of the Org files. Unfortunately, since a3cb9b853 there 
seems to be a behavior change for org-babel-tangle which prevents 
this. An abbreviated stacktrace which shows the error when I try 
to tangle my files:

Debugger entered--Lisp error: (file-error "Opening output file" 
"Permission denied" "/home/n/.emacs.d/early-init.el")
 write-region("" nil "~/.emacs.d/early-init.el" nil 0)

Any way to work around this?
