[Libreoffice] Proofing API Performance

But what if you have an already "finished" sentence that has existed
in the document as such for long, but then go back into it and add or
delete one character, that changes its grammatical correctness in
either direction? (For instance, change "it's" to "its".)

To be able to know whether a sentence is "finished" or not, LO would
have to call some grammar checker, so that it would know if it can
call a grammar checked to check the grammar of the sentence. And what
if the problem with the sentence is that it is incomplete?

Well, who claimed it would be perfect? Improvements to the core code
to make interfacing with external grammar or style checkers more
efficient is very much welcome.
