Currently when Emacs crashes, it keeps a list of affected files in
auto-save-list. Alternatively when opening a file where auto-save
information is more current than the actual file, emacs will display a
message in the status buffer and keep the entry in messages.
However, for novice users, this helpful hint can be easily missed, eg. if a
verbose mode prints messages in the status buffer, like lsp-modes comes to
mind. In such a case the hint that a more recent autosave file exists is
displayed and will get quickly replaced with other messages. If the user is
not aware of recover-this-file, he will likely overwrite more recent
auto-save information with subsequent edits.
I propose that this is bad behaviour and a configuration exists which halts
any further processing until the user actively finishes what a manual
recover-this-file would offer him to do. This feature makes sense,
especially as of Emacs 29? auto-save-files can be reliably deleted by Emacs
itself.

I don't think delaying initialization is a good idea. Instead, how
about using the warnings facility for showing these messages? See the
"Warnings" node in the ELisp Reference manual for more details. In
particular, we have a "delayed warnings" feature, which allows to
delay the actual display of the warnings till after the running
command finishes.
Would you like to work on a patch along these lines?
