Things like changing case can already be done, and smart quotes conversion is better done in plugin settings.
As for numbering why could we not just include the match count as an additional subcapture pattern value allowing the user to reference it in any replacement. Or alternatively just create a plugin that does heading renumbering. A heading renumberer plugin would be the most flexible if you allow the a regex to determine what you are numbering.
What else are people actually using it for that would not be handled better by a plugin.
Having a general user write their own replacement functions in python, edit them, debug them, compile them to bytecode, add and delete them, etc is a lot of overhead and code bloat for just numbering things.
So is this still needed assuming we added a general renumbering plugin controlled by a regex?

I use it in there ways.
1. I use it to Print all matchs, then I can check do I need to improve my regex. I also use Set to combine the same matchs.
2. I use it in match some <span> tag. Maybe because I'm not very familiar with regular expressions, I can not find a good way to match the close tag in html like this.
<span>
<span class="..." style="..."><span><span></span></span><span></span>
</span></span>
So I match all, and parse it in Python.
3. I use it to match condition like class="1 2 3 4" class="3 5 2 1" class="2 6 1 3". They must have 1,2,3, but order is not imortant.
