I think this is a less than ideal workaround because it breaks (Cmd|Ctrl)+F search on large comment threads. I do this quite a bit just to see if some particular topic has already been discussed somewhere. Actually I think the current design is a little unintentionally insidious just because it doesn't make it clear that any comments are being hidden, so if not for seeing this I probably wouldn't have realized for quite a while that there was even a "More" link to click.
