There is an inconsistency here between Org parser and
https://orgmode.org/worg/org-syntax.html + manual.

The actual parser does allow empty lang in src blocks, setting :lang
element property to nil.

Should we stop doing this and treat such src
blocks as paragraphs?

I think that this would cause more of a surprise to the user when something in a source block exports as a plain paragraph instead of in a <pre> block (for HTML exports). 

Or should we allow empty lang and instead adapt
the exporters to treat empty lang correctly?

I vote for this one. Then

#+begin_src

foo

#+end_src

will be analogous to this in Markdown:

```

foo

```
