No, those flags ( -v --runstats --oiio --threads 7 --compression zip --format exr -d half ) won't make a difference.
The MtoA maketx used to support two additional flags, which you aren't using. And I don't think MtoA even uses those two extra flags anymore. If you can't use the maketx from the Arnold distribution, then the only other workaround right now is threads 1 Yes, it's on the radar.
