Yes it does.

The clipboard problem is something unrelated. Terminal applications can
access the macOS clipboard via command line utilities pbcopy and
pbpaste. I'm using the package xclip for that, which is very simple to
use

  ;; Clipboard support in terminal Emacs using pbcopy/pbpaste.
  (use-package xclip :straight t
    :if (not (display-graphic-p))
    :config (xclip-mode 1))

Command-C, Command-V in Terminal.app are used by Terminal.app itself and
not by applications running in the terminal emulator. For example, to
copy shell output or paste something as shell input.

I don't think Terminal.app allows altering Command-V etc. so that Emacs
could use them. Other terminal emulators like iTerm allow doing that.

In summary, this is not a bug.
