I don't see what the point is. You could as well add "NE support" to the FreeDOS kernel.

JWasm is encumbered by the Sybase license. It's OSI "open source" but not FSF "free software". The OpenWatcom relicensing effort isn't fulfilled yet, and even if it were JWasm contributors would also need to agree: https://github.com/Baron-von-Riedesel/JWasm/issues/20

as86 appears to be incompatible to MASM. For instance, immediate operands need a # prefix.

I don't see how NASM is "non-standard", unless you want to define a "standard" as just whatever dialect has the single largest existing code base or whatever tool has been the single most popular choice at one point in time.

I don't see a need for it, nor do I know how exactly this support should work. So I won't add it.
