I also think Org-mode table src block content to override file is dangerous.

I have another idea. Append src block content to end of file.

I have a sceniro:

File `dotfile-1.org`:
```
* SSH config 1

#+BEGIN_SRC conf :tangle "~/.ssh/config"
fragment 1
#+END_SRC
```

File `dotfile-2.org`:
```
* SSH config 2

#+BEGIN_SRC conf :tangle "~/.ssh/config"
fragment 2
#+END_SRC

```

When the tangle src blocks are in separate files, this override file way is
not suitable.
Of course I can put those src blcoks together, but when I have to organize
literate programming files in separately, the override way is not suitable
anymore. So hope Org-mode can provide `append` way with an `defcustom`
option.
