RE the second aspect: that's why I'm a fan of LSP and the related debugging server protocol. There's no way Emacs can have native IDE-like support for all the languages out there, and the small developer base makes it hard to compete with IDEs for popular languages, that have commercial interests backing them. LSP promises to level the playing field - it only takes one good language server to make IDE features suddenly available not just for IDEs, but also Emacs and Vim and others.
