No. That doesn't answer the question or respond to
the bug report.  That just says what the status quo
is that the report reports should be fixed.

This is what should be done, as already pointed out:

  What we should do is just restore the definition
  of `dired-shrink-to-fit' (perhaps even making it
  a constant with value `t'), or just replace
  occurrences of it with `t' and declare it obsolete
  but without such a silly warning that tells you to
  customize `display-buffer-alist'.
