1. As you will already know, to put a link that shows the logs of a page (let's say the "Example" page), we have to write "https://mediawiki.org/wiki/Special:log?page=Example", "[/mediawiki.org/wiki/special:log?page=example]" or "{{fullurl:special:log|page=example}}", I would suggest that just writing "{{Special:log|page=example}}", instead of ignoring any character after the pipe/vertical bar ("|"), have it (into account) as a parameter separator like "{{Special:Prefixindex/Editnotices|namespace=10|stripprefix=1}}" does, not only on that special log page, but also on any other special page. 2. We can write [[Special:Log/create]] rather than "https://mediawiki.org/wiki/Special:Log/create" or "https://mediawiki.org/w/index.php?title=Special:Log&type=create" to view log of pages created, but with subtypes of a log type cannot use double square brackets, if we want to see the page restoration logs, we have to write obligatory "https://mediawiki.org/wiki/Special:log/delete?subtype=restore" or "{{fullurl:Special:Log/delete|subtype=restore}}", if "delete" or any other type of log (that has subtypes), is not added, the subtype is simply ignored, but that has nothing to do with this 2nd implementation, I suggest that the system can show the same page logs when instead of having "?subtype=<name of a subtype log>" in the URL it had "/<name of a subtype log>", the shortest URL to display restore logs would be "https://mediawiki.org/wiki/Special:log/delete/restore" instead of "https://mediawiki.org/wiki/Special:log/delete?subtype=restore", so, we could go to that page by just typing "[[Special:log/delete/restore]]" instead of having to type the full URL or using "{{fullurl}}", and furthermore, with that implementation, we could also see Pppery's modified block logs writing "[[Special:Log/block/reblock/Pppery]]" instead of "{{fullurl:Special:Log/block/Pppery|subtype=reblock}}", It would also be valid to write "https://mediawiki.org/wiki/special:log?type=block/reblock"
If they are implemented, we would save ourselves from writing full URLs or using {{fullurl}}
