Snippets can be distributed as files, but that's not a very good way as I
see it today. One of the  reasons might be too leverage the TAB and menu
expansion of the yasnippet system. But probably you don't want this, and
snippets can also be defined programmatically, albeit not with a beautiful
language.

Are there any major modes which provide snippets

That's because yasnippet is not part of the Emacs repo proper, i.e. the
"core". So adding snippets to major modes in the core would introduce into
the core a dependency on an non-core ELPA package.

Nevertheless, there are ways to conditionally provide functionality based
on whether the non-core package is detected.  A soft dependency. In my
opinion it makes sense for popular non-core packages: company,
markdown-mode, yasnippet, etc. Look at Eglot, for example.
