   i don't understand what you mean by transparent, here.

 Easy to understand.  
 Simple. 
 Direct.

Since `append-to-file' is just a wrapper for `write-region', using
`write-region' to stand for itself is clearer, hence "more
transparent".  Also the complications of advice can be avoided,
again, making the code clearer.
