Don't know if its relevant but your coding parameters are slightly
different to the one's I use for D10, and I wonder if this affects the
automatic metadata insertion..
"-flags +ildct+ilme+low_delay"
Well ilme seems kind of redundant for I frame only coding but probably
harmless.
"-tag:v mx5p"
irrelevant for mxf, but again probably harmless.
I use the following which you do not:-
-rc_max_vbv_use 1
-rc_min_vbv_use 1
and you use the following that I do not:-
"-qmax 3 -rc_buf_aggressivity 0.25"
I don't know what difference, if any, those changes make, but the values
I use create D10 files that BBC R&D looked at and thought were OK.
Perhaps worth a try?
I tried it with your settings but ffmpeg did not encoded it, I became

Error while opening encoder for output stream #0:0 - maybe incorrect
