There is a case where main can be imported. You can import main from a test 
in the same directory, but with a different package name. AFAICT, this 
allows 'external' testing of executable code. In that case what identifiers 
are exported does matter. But since most of us will probably never use this 
feature, it probably does not matter much in practice.

I generally do the reverse.

Everything is internal, lower case, until and unless I need it 
elsewhere.  Then I reevaluate where the boundaries should be at that time.


I often find that as an exported API, I need/want different things out 
of it than I did when it was internal.

Personally, I tend to do it. Note that it doesn't actually make a
difference from a technical perspective - main can't be imported, so it
makes no real sense to export any identifiers. As such, the boundaries of
what I "export" are somewhat more fluent than usual. But yeah, as you said,
for clarity, I tend to emphasize the most important functions this way.
Also, I usually *intend* to factor more stuff out of the main package over
time, as it makes sense (so I start with main and then split it up further
and further) and the same functions then end up being the natural API
points to make that split and it's nice to ear-mark them ahead of time.

At the end of the day, it's just preference and so there's even less of a
"right" or "wrong" answer than usual. Just do it like you prefer, as long
as your team is fine with it :)
