Some select points:

If it works with &useuserjs&useusercss, it's not the system that's at fault. I oubt they're going to review everyone's personal css, or fix it upon request - try the Dev wiki's discord.

" and ” are not the same symbol. The former is used for markup.

The Article comments are using Feeds technology like Discussions. There's not going to be an option to change it to (resembling) the retired code.

Any custom CSS styling solutions will probably be thought up by users over time, it won't be here this early.
