The biggest consequence here is GLIB (and thus GObject). I know that the GNOME GLib project is not interested in porting GLib to WASM at all.

So my solutions are:

1. Hack it so it work on WASM. I'm not sure about this one, I know it can be done, but I'm not convinced on it, also due to licensing it can become a problem for thing like console development for example.

2. Write my own replacement for GLIB. That would be insane. But. I'm not using all GLib, and I'm avoiding GObject stuff as well.
