In what sense?  As of 28.2, practically every library included with
the emacs distribution that can be loaded successfully can be followed
by an invocation of dump-emacs-portable without an error, and
certainly without any core dumps.  Those dump files can also be loaded
successfully.
The normal-top-level function is brittle, as is the system for setting
customization variables at startup.  But those issues are separate
from the redumping functionality, by which I only mean invoking
dump-emacs-portable outside of dump-mode.
