Very good, just two issues:
- you allow repeat#set() to remap keys returned by getreg('.')
- you do :augroup! while there are active autocmds from that group


nmap A <Plug>(Append)
nn gA A

nmap <Plug>(Append) <SID>(Append)
nn <script> <Plug>(LastAppend) <SID>(Append)<C-A><Esc>

nn <expr><silent> <SID>(Append) ':<C-U><BS>'. <sid>AppendSetup(). 'g_'. (v:count ? v:count : ''). 'a'

augroup RepeatCustom
augroup End

func! <sid>AppendSetup()
au! RepeatCustom InsertLeave * call repeat#set("\<Plug>(LastAppend)", v:count1)| au! RepeatCustom
return ""
endfunc
