That seems to me to deny basic facts. The comments are a record of a discussion, editing them to say something different destroys that record.
Currently, the record can be destroyed by deleting it, so I don't see this as a big deal.
It doesn't happen very often, but it is quite irksome when someone edits their comment so my reply doesn't make sense.
That's often a compliment.
At 2011-04-08 LW user account deletion is broken. We (Trike) will fix it… but how should it work?
