Sure, there are absolutely good uses for modal dialogs (not many, but
they definitely exist). I don't have anything against having modal
elements available to web apps. This is in fact what
HTMLDialogElement.showModal() would do in a sane way.

window.showModalDialog() was an attempt to provide roughly the same
thing but it was IMO pretty badly thought out. It's telling that even
after several years not a single browser gets it right: Chrome does
not do modal dialogs at all. If I recall correctly Firefox and IE do
implement modal dialogs, but the modality covers the whole app: you
can't do _anything_  in the browser if one tab has a dialog open. All
of the implementations I've seen are also butt ugly, because you have
to leave some browser chrome in the dialog because otherwise it could
be impossible to close it (which would be disastrous since the rest of
the browser is locked as well).

This article sums my opinion pretty well:
