This was an intentional change, yes.
And AFAICT, it _is_ documented in the ELisp Reference manual:
-- Command: normal-mode &optional find-file
This function establishes the proper major mode and buffer-local
variable bindings for the current buffer. It calls ‘set-auto-mode’
(see below). As of Emacs 26.1, it no longer runs
‘hack-local-variables’, this now being done in ‘run-mode-hooks’ at
the initialization of major modes (*note Mode Hooks::).
And the documentation of run-mode-hooks says:
-- Function: run-mode-hooks &rest hookvars
Major modes should run their mode hook using this function. It is
similar to ‘run-hooks’ (*note Hooks::), but it also runs
‘change-major-mode-after-body-hook’, ‘hack-local-variables’ (when
the buffer is visiting a file) (*note File Local Variables::) ^^^^
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The user manual indeed didn't mention this caveat; I've now mentioned
that aspect there (and also in the doc strings of the relevant
functions).
(The change in Emacs 26 that caused this as a side effect was to fix
bug#15577 and bug#23407.)

I think such a warning could be an annoyance.
