The pwd(1) utility has this limitation for simplicity. The getwd(2)
function and fd2path(2) syscall can work on arbitrary-sized buffers.
So, to overcome the limit, you have few choices:
 1) modify the pwd.c to allocate more memory; or
 2) bind not-so-long parts of your path to /n/something to construct a
namespace with shorter absolute paths; or
 3) blame the tree holders.
