There is no way to intercept *before* loading Vim runtime files

[tyru]

I use https://github.com/itchyny/vim-parenmatch instead of Vim default matchparen.vim,
because it is x8 faster than the default.

I want to write let g:loaded_matchparen = 1 in plugconf file (not vimrc), but bundled plugconf file is loaded after Vim runtime files are loaded.
I need a way to execute Vim script before loading runtime files.
But it must be intrusive feature, because it cannot achieve while depending on Vim packages feature.

First idea

Write

packadd volt_sys
call volt_sys#init()

in user's vimrc and execute pre-scripts.

But this idea breaks zero configuration !!!
