My 2 ören is that it is normal for there to exist several different
Emacs packages that provide similar functionality, and this goes for
more or less any functionality you can think of.

In my case I like to try all the different alternatives at once, so I
write some code to be able to switch between the alternatives on the
fly, until I feel I like one of the alternatives more than the others.

I did this for the gazillion of completion options out there until I
wound up with Vertico, and for the different fancy Modelines until I
just reverted to the OOTB modeline. 

Its not really easy to write such feature switching code reliably
however. Sometimes you wind up in the tedium of rebooting Emacs. (not
too bad though, this Emacs has 80 day uptime)

Maybe having more alternatives in Elpa/Melpa would actually lead to more
code re-use between the alternatives? That would be nice but I guess
history indicates otherwise.

PS

Heres an example of the ugly code I wrote, I used the "daf" prefix for
"dumb alternatives framework". Again, super ugly, but it kinda
illustrates that its not super obvious how to change between similar 
implementations.

      (defun daf-ivy ()
        "Switch to ivy."
        (interactive)
        (helm-mode -1)
        (ivy-mode 1)
        (counsel-mode 1)

        (counsel-projectile-mode)

        (global-set-key (kbd "M-x") 'counsel-M-x)
        (global-set-key (kbd "C-x C-f") 'counsel-find-file)
        (global-set-key (kbd "M-s M-s") 'swiper)
        (global-set-key (kbd "M-y")     'counsel-yank-pop)
        (global-set-key (kbd "C-x b") 'ivy-switch-buffer)
        (setq read-file-name-function 'read-file-name-default)
        (all-the-icons-ivy-setup)
        )

      ;; use flex matching in ivy. its cool!
      ;; but maybe swiper should have another valuse
      ;; (setq ivy-re-builders-alist
      ;;       '((t . ivy--regex-fuzzy)))

      ;;also u can change the re-builder on the fly
      (setq ivy-re-builders-alist
            '((swiper . ivy--regex-plus)
            (t . ivy--regex-plus)
              (fuzzy      . ivy--regex-fuzzy)))

      (setq ivy-initial-inputs-alist nil)


      (defun daf-helm ()
        "Switch to helm."
        (interactive)
        (ivy-mode -1)
        (helm-mode 1)

        (global-set-key (kbd "M-x") 'helm-M-x)
        (global-set-key (kbd "C-x C-f") 'helm-find-files)
        (global-set-key (kbd "M-s M-s") 'helm-swoop)
        (global-set-key (kbd "M-y")     'helm-show-kill-ring)
        (global-set-key (kbd "C-x b") 'helm-mini)
        ;;(setq read-file-name-function 'read-file-name-default);; for helm?
