"It can cause problems with any comments you've posted (either using that OpenID or comments brought in by the importer)."

what are the problems, do you know? I don't want to associate my LJ openID with my DW accnt, so was planning to delete it because I didn't want it clogging up the system if I'm not using it. But I know that some of my LJ friends imported journals that I commented on (at livejournal, not here) so if it will cause serious problems I might not want to. I just thought if I deleted it, it would get a strike through the account name on the comments like a deleted accnt... is that not the case?
