i tried to apply this and make it work but

it breaks fate
also i get random crashes with this with fuzzed files

i dont know if this issue is specific to old versions of libopenjpeg
ill push the patch that marks 1.3 as experimantal as that one
definitly doesnt work properly. Ill also fix the fate issue this
patch leads to (as i already fixed it locally) but beyond that i do
not know Its not really fun for me to try to get libopenjpeg working
at least not when ive to deal with distros shiping ancient non
functional versions of it.
Improving our native decoder is at least to me much more fun to work
on
