Hmmm, these are kind of boring? I've seen colored comments a few times, embedding images is also possible in Dr Racket and on TempleOS I'm pretty sure.

Where's all the fun stuff? Debugger features are neat, but outside of this these features just seem tiny and cute and not too exciting.

Even stronger support for structured Treesitter-based editing? (See eg. Helix), proper multicursor support (Helix), both already seem like black magic to me compared to what came before.

What do you do with proper multicursor?

I frequently use it when I need to make some structural changes to consistent code (block replace function name x, add trailing commas, etc). Not sure what more power I am missing.

One of the most powerful features of eg Helix is the ability to very smoothly and easily filter inside your existing selections, or to split them.

I think the focus here is on "selections", as opposed to just "cursors".

So for example, you can select all occurrences of X (say, usage of some global variable), then say "for each of these selections, select the whole function", and then say "select the name of the function".

And bam, this is a (somewhat artificial and forced example), but you assembled a list of all functions with a specific property in a few button presses without ever leaving your editor. This is very close to stuff I do all the time in Helix. This is a godsend when it comes to manipulating (for example) a huge array of JSON data.

Maybe this is all obvious to you, but this seems like the kind of thing that probably still feels like black magic to a lot of programmers, and which certainly hasn't reached all editors yet (most are not focusing on selection editing as a first-class usecase).
