I vote for keeping the ".html" suffix because I can imagine that Texinfo
creates only files with that suffix and it's depends on the web-server
and its configuration if the file is also served when the suffix is
missed in the URL.
Unfortunately, I was not able to verify this in the Texinfo
documentation or source code.
I had to make another adjustment info-test.el to make the test succeed:
Previously, Info-node-for-url failed when the passed manual-name was
neither "emacs" nor "elisp". In particular, it failed for "gnus". Now
that "gnus" is a handled manual-name, it succeeds. But it should still
error when the manual-name is not handled (by the default value of the
newly introduced Info-url-alist).

I gave my best.
