No you weren't.

I've got no problem with the terminal part of st being modularized and
being called from a separate stub that handles how it connects to
other processes.

The particular method I was thinking of to implement the functionality
I want would actually reduce the code complexity of st by removing the
code to allocate PTYs and spawn a child process.

If you removed the spawning code from st, to implement an xterm like
terminal you could have a separate program that allocates a PTY with
itself on the controlling end, and spawns st attached to the other
end, and then execs itself to a shell which inherits the controlling
end of the PTY. That way you've effectively got something that does
the same job, but you've removed complexity from st itself, and you've
increased flexibility.
