I do not think that you can deterministically associate file extension
with major mode. Alternative major modes do exist for some file
extensions (like built-in python.el vs. python-mode.el). Just extension
list may suffice in the simplest scenarios.

In addition, given "foo.txt.org.gpg.gz" may return
("foo.txt" "org" "gpg" "gz") not stripping the first .txt as it never
affects how Emacs opens the file.
