according to at the conventions the printed calendars here (Norway,
but I suspect the rest of Europe is the same), January 1 and 2 do not
belong in week 1 either. Rather, the convention is that at year end,
if a week is split between two years, that week gets the number
belonging to the year that has the most days of that week.

Our cal does not follow that convention, that is, while it displays
December of 2015 correctly,

[Tue Jun 21 18:56:52] peter@elke:~$ cal -w dec 2015
   December 2015
Su Mo Tu We Th Fr Sa
       1  2  3  4  5 [49]
 6  7  8  9 10 11 12 [50]
13 14 15 16 17 18 19 [51]
20 21 22 23 24 25 26 [52]
27 28 29 30 31       [53]

January 2016 comes out wrong (at least according to the convention here)
:

Tue Jun 21 18:56:59] peter@elke:~$ cal -w jan 2016
    January 2016
Su Mo Tu We Th Fr Sa
                1  2 [ 1]
 3  4  5  6  7  8  9 [ 2]
10 11 12 13 14 15 16 [ 3]
17 18 19 20 21 22 23 [ 4]
24 25 26 27 28 29 30 [ 5]
31                   [ 6]


ncal on a FreeBSD system I have within reach does what I had expected:

[Tue Jun 21 18:55:02] peter@rosalita:~$ ncal -w jan 2016
    January 2016
Mo     4 11 18 25
Tu     5 12 19 26
We     6 13 20 27
Th     7 14 21 28
Fr  1  8 15 22 29
Sa  2  9 16 23 30
Su  3 10 17 24 31
   53  1  2  3  4

(ncal on Linux does much of the same, but of course the command line
syntax differs slightly)

I was blissfully unaware of cal -w until you wrote this, and I don't
really care for the diff that started this thread, but having correct
week numbering is to my mind a lot more useful. Then again, there may
be week numbering conventions I'm not aware of (and of course there's
the Monday vs Sunday as week start day issue).
