Seems nobody is addressing the supply-chain issues. If Apple, say, makes the MBP-R battery replaceable: they then have to design for user-replaceability (both battery and case), provide replacement batteries as a separate SKU part, provide covers as a replacement part, include new cases & connectors etc. in the supply chain, devote manufacturing lines to building & packaging user-handleable batteries, ship them as separate products, devote store space to them, deal with return/replacement thereof, provide personnel support/service, and so on ... all for something which 95% of all users won't use or won't care if they can't. Being so keen on minimalism for the sake of cost savings, Apple eliminates a huge cost sink by just gluing long-lasting batteries into a sealed case. Re-routing the savings, they can pour more money into the battery power & longevity and reduce the final product cost, delighting users ... and, of course, increase profits.
