This is currently not customizeable.
If implemented, it can be an extension of the existing
`org-blank-before-new-entry' customization.

Patches welcome!

"Footnote" section line spacing is weird

[James Harkins]

Org-mode 9.5.2 (packaged with Ubuntu 22.04).

I've noticed this for awhile -- wondering if this has changed in a more recent 
version.

Let's say I have, at the bottom of a document:

```
* Footnotes

[fn:..] lorem ipsum...
```

Somewhere else in the document, I do C-c C-x f.

Then I see:

```
* Footnotes


[fn:-]
[fn:..] lorem ipsum...
```

I believe it would make more sense like this:

```
* Footnotes

[fn:-]

[fn:..] lorem ipsum...
```

That is:

- Expected: Position the cursor at the beginning of the first footnote (before 
the bracket). Then insert a new footnote ID followed by two newlines.

- Actual: Position the cursor at the beginning of the first footnote (before 
the bracket). Then insert a newline, a new footnote ID, and another newline.

User impact is that if I don't edit the newlines by hand every time, eventually 
I end up with:

```
* Footnotes:








[fn:xxx]
[fn:yyy]
[fn:zzz]
```

... which... does not strike me as a deliberate result.

Easily reproducible, every time.

In org-customize > Footnote, I don't see a variable related to the insertion 
template.
