I don’t think there’s any LPDDR4 4266 available with ECC, so it couldn’t use it. The error message probably just indicates M1 supports ECC as an option.

  Wouldn't be surprised if this is for the inevitable multi-socket, high-bandwidth M2Z in the inevitable $5,000 Apple Silicon Mac Pro in a few years' time

    Which would be worth every penny, gauging from the M1.

    so ah for what it's worth, leak today was that the next chip is a 12 core m2z, offered as soon as March[1]. rumors. but very believable. current m1 is supposedly 16b transistors at 5nm, a scant 116mm^2. compare to current 7n graphics chips such as an amd 6900 which is 26b transistors & >500mm^2. also notable, the 8 cores on the m1 are only 1/3 of the chip size. it's gpu is bigger. suffice it to say, adding another 50% more cores is not gonna be a problem nor affect yields a lot. if apple wanted to, for whatever reason, dedicate more of that core space to cpu, & chop off that cpu, well, that'd be something. that said, yeah, a multi-socket m[x] chip might not be in the cards for 2021. or maybe it is. anyhow the rumor mill has been floating the ideas of an "m2x" and "m2z" follow up being launched this year; this is just further "suggestion"/priming that we may see one, or two follow ups.

    By “it” you mean the chips have 4266 MT/s LPDDR4X SDRAM and not ECC, right?

But then you have to give Apple money.
