Feature request: Add a limit to the write function to honor the max request size imposed on the Wikibase server

Maybe add a parameter to the write() method to filter the statements you want to update.
Like, you have a huge object, but you only want to update one statement in it, at the moment, WBI don't (and can't) track which statement you update (or not), but when you write you can pass to only send these statement(s) and ignore everything else ?

That is not a solution in my case. I'm compiling the whole item and creating it in one go currently.
I found a workaround: compile up to 500 statements and upload. Then append the rest using wbcreateclaim via wbi helper.
