How to use the matchup_convenience_maps function from lua?

[AckslD]

I tried to do the following:

  vim.api.nvim_exec([[
    xnoremap <sid>(std-I) I
    xnoremap <sid>(std-A) A
    xmap <expr> I mode()=='<c-v>'?'<sid>(std-I)':(v:count?'':'1').'i'
    xmap <expr> A mode()=='<c-v>'?'<sid>(std-A)':(v:count?'':'1').'a'
    for l:v in ['', 'v', 'V', '<c-v>']
      execute 'omap <expr>' l:v.'I%' "(v:count?'':'1').'".l:v."i%'"
      execute 'omap <expr>' l:v.'A%' "(v:count?'':'1').'".l:v."a%'"
    endfor
  ]], false)

but I get the error:

Vim(xnoremap):E81: Using <SID> not in a script context

Nvm, putting it in a function works :)

  vim.api.nvim_exec([[
    function! s:matchup_convenience_maps()
      xnoremap <sid>(std-I) I
      xnoremap <sid>(std-A) A
      xmap <expr> I mode()=='<c-v>'?'<sid>(std-I)':(v:count?'':'1').'i'
      xmap <expr> A mode()=='<c-v>'?'<sid>(std-A)':(v:count?'':'1').'a'
      for l:v in ['', 'v', 'V', '<c-v>']
        execute 'omap <expr>' l:v.'I%' "(v:count?'':'1').'".l:v."i%'"
        execute 'omap <expr>' l:v.'A%' "(v:count?'':'1').'".l:v."a%'"
      endfor
    endfunction
    call s:matchup_convenience_maps()
  ]], false)

Is this something that people commonly use? Never formally supported this because the semantics seemed specific to one user's workflow.
Perhaps a single option to create these would be more convenient.

At least for me using eg I instead of 1i is more convenient :)
