I would think it's a reasonable assumption that BM will add support for the T7 in the near future...
Sorry, but you have got this the wrong way round. BMD firmware supports a specific class of recording media, and has chosen drives that meet BMD’s recording standard, not the other way round. Camera FW is not tailored for any specific drive, but rather for a drive that can provide the sustained writing throughput recording a continuous video requires.
BMD tests specific drives, and determines which ones will work with BMD specifications, then those drives/cards are added to the list. It appears the Samsung T7 didn’t pass the test, and is not suitable for recording the high bandwidth video signal from BMD cameras. Yes not all SSD cards have been tested, but quite a few have been. Some non-tested/approved cards Work for some recording applications, normally for short takes less than 10 minutes, but I would not put a project or job at risk using one, just to save a few $£€.
Time to move on and get a card that is on the list.
Cheers
