Well, this is the consequence of the fix for bug#45245. In etc/NEWS,
this is mentioned as

--8<---------------cut here---------------start------------->8---
*** Writing sensitive auto-save or backup files to the local temporary
directory must be confirmed.  In order to suppress this confirmation,
set user option 'tramp-allow-unsafe-temporary-files' to t.
--8<---------------cut here---------------end--------------->8---

Of course you could set tramp-allow-unsafe-temporary-files to t, but
that's not the idea for a general solution. Tramp uses already some
caches in order to minimize the needed checks, but perhaps it could do
better. I'll check.

Best regards, Michael.
