I've been using 18 for motorway exits for a long time and I find it much
more convenient than current value in default style.
I would also increase resolution for boundary=administrative with
something like:
boundary=administrative & admin_level<3 [0x1c resolution 18]
boundary=administrative & admin_level<5 [0x1c resolution 19]
boundary=administrative & admin_level<7 [0x1c resolution 20]
boundary=administrative & admin_level<9 [0x1c resolution 21]
(not tested though)
