Retention, or the lack thereof, when cold-stored.

In term of SD or standard NAND, not even Nintendo does that. Nintendo builds Macronix XtraROM in their Game Card, which is some proprietary Flash memory with claimed 20 year cold storage retention. And they introduced the 64 GB version only after a lengthy delay, in 2020. So it seems that the (lack of) cold storage performance of standard NAND Flash is viewed by some in the industry as not ready for prime time. Macronix discussed it many years back in a DigiTimes article: https://www.digitimes.com/news/a20120713PR201.html.

And Sony and Microsoft are both still building Blu-ray-based consoles.

Yes. But one should also note that only a limited range of Intel GPU support SR-IOV.

GCC, back in the days DJGPP in particular. As a child in the 1990s I could not afford the big name compilers like Watcom. And compared to DJGPP, all the “prized” Borland/Turbo stuff that my middle school pushed (with segmented real mode), were practically Fisher-Price and Mattel compilers.
