I was thinking that the MVI would be some sort of special character,
limiting the tag to just 3 unique characters. But now I understand it
better. My mistake.

Why not? What's wrong with MVI/MVC for 3?
Given that it would involve no storage references beyond the target and
i-cache, I wonder if the fastest way to set four bytes, without the string
appearing in storage, might not be four sequential MVI's.

I kinda like the concept, but a lot of literals we use are just 4
characters, so it does not scale down easily.
