A little hard to put in the title, but I've thought about this for a while and I may have even mentioned it in other topics.
You may have noticed that when a topic is locked, unless stickied, it gets sent right to the back end of the forum pages, where all the current locked topics are placed, ordered by date.
In the past the whole set of topics on each board were simply organised by date of last post regardless of whether they were locked. Now, no matter the date the locked topics get sent back pages upon pages to be stored at the end.
I think the old system was more convenient. Because a topic is locked doesn't necessarily mean it was due to rulebreaking or for something negative. Posts that seriously breach the community rules are trashed anyway and moderators can hide topic contents if they didn't want people to view what was posted.
