Gads, don't get me started on SPI software upgrades on the Mac Book Pro. Serious cramp in the calvins. Forced non-down-gradable (sp?) OS because of that.

Could you expand on how this causes problems? As far as I'm aware, this has never prevented e.g. downgrading to an older version of macOS. (I assume I would know because I downgrade everything to OS X 10.9.)

Why do you downgrade so far?

A 2012 Macbook Air, a 2014 Macbook Air, and a 2014 Macbook Pro. The 2012 Macbook Air was upgraded to Mojave at one point before it ran Mavericks. I admittedly don't know what OS the two 2014 Macs were running before I bought them in 2020.
