<p>I reject such edits.  </p>

<p>As @Scortchi notes, an initial edit of a closed question bumps it into the reopen queue.  However, if the edit does not address the reason for closure, that thread should be rejected for reopening.  At that point, the OP has lost their first, easiest opportunity for having their question reopened.  (It is still possible for the thread to be reopened, and even for it to enter the reopen queue, but it's not automatic.)  On the other hand, it is possible that, simply by virtue of being in the reopen queue, it will be reopened inappropriately, despite the fact that the problem has not been addressed.  Either way, such edits seem to increase the chance of a poor outcome.  </p>

<p>On the other hand, closed threads are often purged (deleted) <a href="https://stats.stackexchange.com/help/roomba">automatically</a>.  Editing them can interrupt this process.  Even if it doesn't, I don't see much value in having tidier threads deleted instead of messier ones&mdash;in either case they're gone and no one will notice their grammar and spelling.  </p>

<p>In sum, there are several possible downsides and little upside from such edits.  </p>
