A-series will continue with HomePod and Apple TV, but these don’t need more than A12 (same as iPhone) for the foreseeable future..

Power consumption and thermals. The M1 is basically the A14 with slightly higher peak clock rate, 2 more high power/performance cores, 4 more GPU cores and double the memory lanes. The M architecture is based on A architecture, not the other way around.
Really, the M1 is pretty much what the A14X would’ve been but branded differently probably partly so it doesn’t offend the Mac users to know the new Macs are getting an iPad chip. Indeed, because of the change in branding, they can now boast that the latest iPad Pro is getting a Mac chip.
