you will be shocked how many issues in fdt are meanwhile fixed by the ‚ghostwriter`(Sponsored by: Innovate UK)  :-).
see the Wiki-list of features/what works.
I didn`t test the huge-file-thing extensively
 but when our `other U.K-innovator`:-)  says he has fixed it in D26344 that means:
It IS definitely fixed. :-)...  but of course you should continue attacking the board because 
you mostly find out something interesting ;-)
