Hardware decoding for 4:2:2 10-bit .MXF files on Blackwell GPUs?

Question

What's the latest information on when Adobe plans to add support for hardware decoding of 4:2:2 10-bit .MXF files on Nvidia Blackwell GPUs?

Attached is a screenshot from Premiere's debug monitor. I played footage from a Sony A7S III wrapped as .MP4 (X-AVC S 4:2:2 10-bit 3840x2160 23.978) and footage from a Sony FX6 wrapped as .MXF (X-AVC I 4:2:2 10-bit 3840x2160 23.978). You can see in "Importer.MP4" that hardware decoding is being used for the .MP4 footage, and in "Importer.MXF" that hardware decoding is NOT being used for the .MXF footage.

I'm not sure if this is a bug, or if Adobe simply hasn't added this feature yet.
I am on Premiere 26.3.0 and Nvidia Studio Driver 610.62. GPU is RTX 5060 Ti 16GB. OS is Windows 11.

No idea, but as a shooter of MXF for the last 5 years, I’ve learned to rewrap to mov/proress, Premiere seems to never get along with MXF.

LLMs have been pretty good at helpimg me get the best out of FFmpeg.

ffmpeg -i input.mxf \
-map 0 \
-c:v prores_ks \
-profile:v 3 \
-pix_fmt yuv422p10le \
-vendor apl0 \
-bits_per_mb 8000 \
-c:a pcm_s24le \
-movflags +faststart \
output.mov

or single line:
Powershell: ffmpeg -i "input.mxf" -c:v prores_ks -profile:v 3 -pix_fmt yuv422p10le -c:a pcm_s24le "output.mov"

etc.
