Just for the sake of completeness, here is another (very) good reason to allow
such a thing: for Beamer, with the sidebar outer theme, which allows you to
see, on every slide, where you are in the TOC (up to 2 levels).

If you have such a TOC:

--8<---------------cut here---------------start------------->8---
1. Intro
2. The meat
   1. Why?
   2. Why not?
3. Conclusion
--8<---------------cut here---------------end--------------->8---

and have frames level beginning at 3, you would have in Org:

--8<---------------cut here---------------start------------->8---
* Intro

*** Introduction

    This is first slide.

* The meat

** Why?

*** Why to do this?

    Second slide.

** Why not?

*** Why not to do this?

    Third slide.

* Conclusion

*** Conclusion

    Last slide.
--8<---------------cut here---------------end--------------->8---

So, the solutions are:

1. To allow for skipped levels
   -> Sidebar is exactly as it should.

2. Not to export skipped levels
   -> You need to insert a level-2 for the Introduction and Conclusion

   a. Empty title (such as `** ')
      -> Empty space in the TOC displayed in the sidebar
      -> Bad!

   b. Repeat the title of level-1
      -> Not nice...

So, allowing for skipped levels seems the only nice way for me. Did you follow
me?

Best regards,
  Seb
