Indeed preparing good names for completion makes them easier to type.
For example, recently after adding the "tab-bar-mouse" command made harder to
enable "tab-bar-mode" by typing just "tab-b-mo", it doesn't complete anymore.
Also better would be to group all related commands under one prefix,
such as "tab-next", "tab-previous" for easier completion.

Please try to find evidence that more people have the same problem
with completion.  For example, I have in my init file such aliases
that I often mistype, e.g.:

  (defalias 'comapre-windows 'compare-windows)

because "comapre" is easier to type than "compare" on a qwerty keyboard :)

Another solution is to make completion smarter, like when in bash
mistyping a shell command still find it by correcting its name.
