I can understand why you'd think that, but allow me to correct. My view
is biased by the fact that I built the _first_ such library, and it was
pretty annoying, and I want to save future programmers from this
unnecessary annoyance. And that we're working on language support that
virtually guarantees that others will want to write similar Java
libraries. If this were just about compilers emitting bytecode, I

I am saying that I imagine a future where the number of people writing
BSMs for condy is at least 100x bigger than it has been historically.
Again, if I thought this was just about me and you and Charlie, I
wouldn't care. But I don't think that's the case here.
