No. And that’s one of the reasons why running Mac apps on iPadOS wouldn’t work. Other reasons are that they would have to provide a multitude of macOS APIs on iPadOS, emulate a compatible file-system structure, and further difficulties along those lines. People should understand that this won’t be happening.
You seem to be forgetting that MAS-distributed apps already use containerization, meaning, it would be extremely easy for Apple to provide that same filesystem structure, much in the same way that certain iPad apps can already run on Apple Silicon Macs.
Also, have you ever SSH-ed into any of Apple’s mobile devices or disassembled an .ipsw image from an iOS or iPadOS build? I personally haven’t, but I’ve seen it done before, and the filesystem structure is already good ol’ Apple’s semi-proprietary Mac OS X’s BSD-based Unix under the hood (I’m going with the vintage branding, just so we’re all on the same page).
About the only recent-ish Apple devices that didn’t have it were the classic scroll/touch/clickwheel iPods and, surprisingly, even the later touch-screen-based nanos, whose OS was based on
Pixo’s solution instead, which was perfectly understandable, as the OG iPod was still compatible with iTunes 1.x on Mac OS 9 and OS X was still a comparatively unoptimized, bloated mess back then (or at the very least overkill for the currently available and compatible PowerPC hardware, let alone for a puny, pre-TSMC ARM processor from the era).
