bug#50510: 27.1; open/create ada source file

[Christophe via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hello,
from 'emacs -Q' or not:
- starting emacs
- C-x C-f test.adb
=> return this error

Debugger entered--Lisp error: (void-function ada-mode)
  ada-mode()
  set-auto-mode-0(ada-mode nil)
  set-auto-mode()
  normal-mode(t)
  after-find-file(t t)
  find-file-noselect-1(#<buffer test.adb> "~/test.adb" nil nil "~/test.adb" nil)
  find-file-noselect("/home/mutenroshii/test.adb" nil nil)
  ido-file-internal(raise-frame)
  ido-find-file()
  funcall-interactively(ido-find-file)
  call-interactively(ido-find-file nil nil)
  command-execute(ido-find-file)

The elpa ada-mode is not installed, but that was not an issue with emacs 26.1.
That means thre are no more built-in ada mode like befor ?
Is there any way to manage ada source files without trying to install the elpa
'package' ?
Thanks.

Thanks for the link.
I am not disagree with the fact there is a package in elpa, but I'd prefer we
have the choice between the built-in and the elpa.

thanks and best regard.
