Surround text is usually the current paragraph or sentence. Use-case is
text prediction via text n-grams for instance, which only needs a few
neighboring words to work out.

I'd be curious to know which use-cases you tried to implement to hit the
buffer limit. That is, if you can disclose them of course.

That's a property of the text editor, not necessarily the input method.
Read: client-side decision/controlled by UI toolkit.

Could you please explain in more detail? Sounds as if you think some
parameter or such is missing. There's always the possibility we got some
details wrong when designing the protocol ;-)
