It’s you who sees it as excuses. If I have a screwdriver multitool, I don’t need another one which is for d10 only. It simply creates unnecessary clutter in a toolbox. The difference between definition and mention search for a function is:

  gr<bs><bs>ion name<cr>
  vs
  grname<cr>

or for the current identifier, simply

  gr<m-w><cr>

I could even make my own useful tools like “\[fvm]gr” for function, variable or field search and brag about it watching miserable ide guys from the high balcony, but ain’t that unnecessary as well.
