The only way the patch could break an existing plugin is if the plugin relies
on text-object commands which are not yet defined failing. This is
theoretically possible but very hacky - I have a hard time imagining it being
used. Even _if_ such a thing existed, it could simply disable the setting for
the plugin's duration.
FWIW, here's some code that will operate differently if the patch is used and
the setting is set:
:execute "normal! i$foo$\<esc>ci$Abar\<esc>"
Off the top of my head I can't see why that would be explicitly desired, but
even if it does exist, the plugin can simply disable the new setting my patch
adds for it's duration.
If a plugin tries to map something like "di$" it can still do so - the map will
outprioritize Vim's default actions.
