It's a little hard to evaluate in isolation, but here are a few comments:

Why are the latter two variables being added to the customize framework?

They seem like low-level variables that are only exported to lisp for
the terminal lisp files to use, not something that a user would
customize.

Why use `set-variable' instead of `set', or indeed, instead of just `setq'?

term.c is not particularly consistent, but in general the naming
convention used seems to be either `set_terminal_foo' or `set_tty_foo'.

I find the name `tty-frame-use-title' a bit odd; how about something
like `tty-show-frame-titles' (it's the first three words of the
docstring, which must mean something :-)?
