It did worry me though, as I had also never heard of it. Is it highly available like more regular DIMM or SODIMM ram?
That is usually my concern with things like the modular ports and replaceable keyboards too. By the time I actually need to replace anything it could be 10 years from now, could I actually source these parts easily?
Regardless, that is a excellent problem to have compared to other less repairable laptops. I have been running my current laptop for 10 years, by the time it's unrepairable I might switch to this.
If this model of laptop is produced in high volume, at minimum it means that dead ones can be used for parts to cobble together a smaller number of functional ones. Well, unless it turns out that a design flaw means a few parts in particular are almost always the first to go...
