No, we can't maintain cruft indefinitely.  The complicated interaction
between default-frame-alist and tool/menu bar mode needed simplifying.

The default value of `default-frame-alist' is now nil, unless you
explicitly set the value to something else.  It is a properly-behaved
defcustom (and so is `initial-frame-alist'); Emacs does not muck with
the value when starting up, nor when you run the `*-bar-mode' commands.

Conceptually, adding any element to `default-frame-alist' is like
implicitly supplying an argument to `make-frame'.  (Any actual argument
you supply to `make-frame' takes precedence over `default-frame-alist'.)

If no `tool-bar-lines' or `menu-bar-lines' parameter is supplied in the
`make-frame' arguments or `default-frame-alist', Emacs sets the value
from the value of `menu-bar-mode' and `tool-bar-mode'.

You are likely setting a non-zero `tool-bar-lines' in
`default-frame-alist'.  I don't know why you would want to do this, if
your intention is to disable the tool bar.  As far as I can see, there
is no bug here.
