Disable or change an augroup for a particular filetype?

Hi!

What would be the best way to 1) disable or 2) change an augroup for some filetype? For now, in my after/ftplugin/some_filetype.vim, I have something like this (not at the same time, of course):

" if I want to disable it
augroup DisableMyAugroup
autocmd!
autocmd BufEnter,BufWinEnter,WinEnter,TabEnter <buffer> autocmd! MyAugroup
augroup END

" if I want to change it
function! s:ChangeMyAugroup()
augroup MyAugroup
autocmd!
autocmd SomeEvent <buffer> MY_NEW_COMMAND
augroup END
endfunction
autocmd! BufEnter,BufWinEnter,WinEnter,TabEnter <buffer> call <SID>ChangeMyAugroup()

function! s:RestoreMyAugroup
augroup MyAugroup
autocmd!
autocmd SomeEvent * MY_ORIGINAL_COMMAND
augroup END
endfunction
autocmd! BufLeave <buffer> call <SID>RestoreMyAugroup()

It works OK, and I seem to have no problems with it but may be it can be tweaked in some way or enhanced? Any suggestions?


Thank you for your time :)
