Thanks for considering coreutils!
As for this particular functionality, it definitely _is_ useful.
I myself use this alias:

  alias tail='tail -n $((${LINES:-12}-2))'

However considering the relatively simple alias to achieve this functionality
it's probably better to not couple that within tail itself.

Would you perhaps consider some other coreutils patch?
For example it would be useful for `sort --debug` to print extra info.
 1. print memory space available.
   I.E. allocated internal buffer sizes and space avail at $TMPDIR(s)
 2. output if locale is specific to the sort.
   I.E. if strcoll() and memcmp() differ in direction
