I don't think it's a good idea, it's part of the standard. We have smaller (legitime) mail servers receiving mails having only A record. Why would I need MX record, if A is ok for me? I only set up MX records when it's needed (the DNS name itself has an A record already but MTA receiving its mail is not at the same address as A record would tell), otherwise I leave it alone with the A record only. I think there is no problem with this practice. - Gábor
