Since their whole pricing strategy depends on users not being able to do RAM and storage upgrades, you can be sure they'd rather make the integration even more tight in the next models.
My understanding is that the ram is basically in the Mseries die and therefore can't really be upgraded. The storage is pure malice or marketing pushing for 'thinnest laptop'

Kinda, the SSD controller is integrated into the M-series SoC so even if the storage were slotted (as it is in the Macs mini, Studio, and Pro) you wouldn’t be able to use an off-the-shelf M.2 SSD since the storage is little more than raw flash on a card for those models.
Sure they could make their own new standard slot or whatever. Tossing out a perfectly good motherboard and cpu to replace some flash is god damned ridiculous.
