You can copy it over, it  doesn't really need breadcrumbs, though,
it just needs imenu.

The only things I'm seeing in its implementation in a penchant
for a particular text property `breadcrumb-region`, which
has information that imenu's structure didn't have a good
place to place.  But it's not required, as you noticed, I  suppose
it just gives it increased accuracy.

Yes, that's the point.  Though when using Eglot, the exact tree
structure -- of any -- depends on the language server.
