In the cases I faced, I found it a drawback that the current buffer is
treated differently than the others by current-window-configuration:

Suppose it did not make such an exception. Then it would be quite easy
to manually implement exceptional behaviour for the current buffer. But
the converse is not so easy: It is harder to manually obtain the desired
behaviour if we *want* the current buffer to be treated like the others,
when the function already treats it differently. If it didn't, then a
simple save-excursion, or a similar mechanisms, around restoring the
window configuration could ostensibly restore the state for all buffers
except the current one, resulting in the same behaviour that we get now.
At least that was my impression when using window configurations.
