Actually, `dolist' is a macro from "subr.el", which is then shadowed by
`cl-dolist', so there's no problem here.

BTW, you can use macros from cl (cl-lib doesn't exist in Emacs 23), not
so functions.

I wasn't clear. A "leading hline" is when the very first row is a hline
(or worse consecutive hlines start the table). In the example above,
there is no such leading hline, so you don't eliminate it. Therefore,
only header will be skipped.

There is a header. By definition, anything in the first column group is
a header. There is no limitations on the number of rows involved.

It may be a bit surprising, but this is consistent with the rest of Org.

See above.
