Not really, see below (and your own conclusions are different as well).

This doesn't sound like "Emacs lacks" the feature.  It's not even
partial.  It is just different from what you'd like it to be.

You can use the menu bar if you don't remember the command.

You can disable the "breadcrumbs" display by toggling an option, if
you don't like it.  But note that they are clickable, so they provide
yet another navigation aid, one that Web browsers generally lack.

Emacs doesn't lack that: you can copy the current node name to the
kill ring (and consequently to the clipboard) using the
Info-copy-current-node-name command.  This enables #5.

YMMV, but I'm always tremendously annoyed by Google oh-so-helpful
decision what language I want to see my pages in.  I hope Emacs will
never follow that particular suit.
