https://www.mediawiki.org/wiki/Manual:Block_and_unblock#URL_parameters probably needs an update after the introduction of partial blocks. For example, passing wpCreateAccount via an URL such as https://meta.wikimedia.org/w/index.php?title=Special:Block&wpTarget=Example~metawiki&wpExpiry=infinite&wpHardBlock=0&wpAutoBlock=0&wpCreateAccount=0&wpReason=other&wpReason-other=Test will have the "account creation" checkbox marked despite wpCreateAccount=0. I checked SpecialBlock.php but CreateAccount is still called as such, thus no idea how to fix this.
Another question is to document if it is possible to pass URL parameters to perform partial blocks, its options, etc.
Thank you.
