Hey! That's an awesome idea.
Expanding on the idea
---------------------
We need to specify the target column ("consumption" in this example).
Therefore, the formula could be something like that:
$4 = fit (consumption = ? +?*year +?*passengers +?*(year-2016)*passengers)
It would benefit from other spreadsheet features, like constants and
remote references.
On the development side, the TBLFM handling is already quite a big chunk
of code. We must take care that such an additional feature do not add
complexity and maintenance burden.
Orgtbl-fit as-is
----------------
It is also possible to include orgtbl-fit as-is into Org Mode core. It
would sit side-by-side with the core without changing anything in its
code and its unit-tests.
Data-analysis toolkit
---------------------
From a higher perspective, we could give a consistent data-analysis
toolkit to Org Mode (and call it org-data-analysis.el).
It would start with fitting, clustering & aggregation. Then, new
algorithms would be added upon user requests.
Of course, there should be an interest among Org Mode users for such a
toolkit.
