If we get flooded with such hardware cheap, there's no reason to use consumer desktops anymore (except, maybe, energy saving).

I use registered platforms, too. But the problem is that everything DDR5 registered has been very expensive as far as motherboards are concerned. Every old EPYC boards for DDR4 have always cost a premium. Even when RAM and CPUs were cheap.
 
Yeah, that's true, I remember raising an eyebrow when I bought the RAM. I just checked my eBay records… 128 GB of DDR4 RDIMM ECC for €159 in mid-January 2025 (that would be $163 at the time). A far cry from current DDR5 prices, but still enough to surprise me at the time (but we were already at the start of the rise of memory prices as well).

But well, a buyer market in datacenter hardware may be precisely what will change that. Hope does not kill anyway. :)

EDIT: I just checked, the exact same RAM (same manufacturer, size and specs) would have costed me today €825…

So you can't use the RAM in consumer platforms if and when it gets dumped on the market after a crash.

I consider the absense of registered (buffered) / ECC supports on consumer platforms to be fatal.
All SHALL support it, even if mostly used with unbuffered / non-ECC {SO-}DIMMs. Letting users to choose SHALL be considered MANDATORY.
 
Some Intel boards will support both ECC and unbuffered types.

My Xeon boards are SuperMicro and support both. I picked up 128gb before the huge increases

Unfortunately that party is over with DDR5. DDR5 registered modules have different sockets from unbuffered.

Oh...
So it would be hard for notebooks and miniITX boards if SO-DIMMs are on the same approach.

Conclusion:
Notebooks (including SoCs / chipsets) SHALL dispose unbuffered / non-ECC support and mandate registered (buffered) / ECC.

Motherboards for consumer desktops SHALL implement both sockets or registered (buffered) / ECC only.

JEDEC SHALL NOT PROVIDE REFERENCE DESIGN FOR UNBUFFERED / NON-ECC MEMORY MODULES.

Give users chance to replace unbuffered / non-ECC RAMs shipped with PCs to registered / ECC (at worst, unbuffered / ECC) RAMs for consumer grade PCs!
