As discussed a few times this is technically challenging to do.

All of “classic” is visible from /var/lib/snapd/hostfs/ but there is no guarantee that you can run them in any way. They may require the classic dynamic linker, the classic runtime libraries and the classic filesystem layout that are all lost when snap-confine sets up the execution environment. If there’s desire to run executables from the outside we could look for solutions but this is not as simple as “just use devmode”
