Another point is stuff that is soldered in is a lot more reliable as a whole. Amazing how many old machines can be resurrected by reseating the RAM.
Really I'm on the fence. I'm sitting here on a 16Gb M1 MBA also.
Now what I really want to see is replaceable USB-C ports. Those have a massive repair and replacement risk over the normal lifetime of a laptop. Lenovo / Dell etc solder them directly to the motherboard. One bad knock and the whole thing goes in the trash. At least Apple stick them on a daughterboard.
