It's possible, but not easy. Similar issues as in Lua bytecode.

Then you'd need to embed decompilers for all variants. That's not
exactly an easier job.

Bytecode format changes are a deployment problem. But not more so
than updates to the core VM. In a properly set up project a
simple 'make' ought to re-translate and rebuild everything.

[And no, I do _not_ want to create another javaesque 'binary-only'
ecosystem, shipping obfuscated bytecode plus the ensuing arms race
with decompilers. That's just so depressing to see.]
