is this comment correct?

why not? the latest com_joomlaupdate can be installed on accident jomla versions not supporting that feature.

[brianteeman]

it doesnt seem to be relevant to that code

Can you please explain what you mean by that? The code mention checks whether there is support for the reinstall attribute or not and handle that case differently. In the line just after this comment it calls the new signature so to me this is still perfectly valid.

But I'm fine to change the text on your suggestion if required.
