I did. It starts from

  if (config_maxword && buf_len(buf) > config_maxword) {
      fatal("word too long", EC_IOERR);
  }

and hits that final

  lib/libconfig.c:    config_maxword = config_getint(IMAPOPT_MAXWORD);

It seems we are fucked up by admin configurations. But I still have no
idea what that value is by default.

As it could be changed, I'm inclined to take that arbitrary value. That
said, it may be nice to introduce a new configuration option.

It does to me. :-)
